A group of 4 couples heading for the Black Hills Sunday, riding quads out of Mt Meadows by Hill City. We did the same trip last year, awesome scenery
Due to many applications, there is also a wide variety of O-ring material choices available. One MUST determine what material any individual “o”ring is made of and decide if that material is suitable for the application.
Factors to Consider When Picking O-rings
When picking the right O-ring for your specific application, there are many factors to consider. They include but are not limited to operating conditions, chemical compatibility, sealing pressure, temperature, durometer, size, and cost. Depending on the specific situation, you may also look at abrasion, tear, ozone, electrical resistance properties. Additionally, you can perform appropriate field tests to ensure the fluid, temperature, pressure, and environmental conditions are compatible with the O-ring of your choice.
O-ring Material Selection Guide
In order to accommodate a large variety of applications, manufacturers make O-rings and seals using various elastomers with different physical and chemical properties. Let’s look at some of them below:Nitrile Butadiene Rubber (NBR)
Resistant to: Water, Petroleum Oils & Fluids, and Hydraulic FluidsNot recommended for: Phosphate ester base hydraulic fluids, automotive brake fluids, ketones, strong acids, ozone, freons, halogenated hydrocarbons, and methanol
Temperature Range: -40° to +250°F, although that’s an average for the lower and upper tolerances for the various nitrile butadiene rubber (NBR) compounds manufactured by Parker. Parker’s Buna-N compound, which ranges from 70 to 90 durometer hardness nitrile, withstands temperatures from -30°F up to 250°F which includes compounds N0674
Hardness: 40 to 90 durometers Shore A
Buna Nitrile
Most popular elastomer O-ring material. Parker Hannifin uses 70 durometer hard nitrile (Buna-N) for most of its standard O-rings supplied, with 90 durometer available for tube fittings and adapters. Seal professionals value Buna-Nitrile elastomer for competitive price and excellent resistance properties to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water, and alcohols.Ethylene-Propylene (EPDM)
EPDM has a spotless reputation in the sealing world because of its excellent resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight (UV). Nevertheless, experts do not recommend EPDM compounds for gasoline, petroleum oil and grease, and hydrocarbon environments.Resistant to: Extreme cold, steam, hot water, sunlight and UV, dilute acids, ketones, alkalis
Not recommended for: Petroleum base oils and di-ester base lubricants
Temperature Range: -65° to +450°F
Hardness Range: 40 to 90 durometers Shore A
Neoprene (CR)
Neoprene is a general-purpose elastomer with moderate resistance properties to petroleum oils and weather (ozone, sunlight, UV, and oxygen). Neoprene O-rings have a relatively low compression set, good resilience, abrasion, and are flex cracking resistant.Resistant to: Refrigerants (freons, ammonia), high aniline point petroleum oils, mild acids, and silicate ester lubricants
Not recommended for: Phosphate ester fluids and ketones
Temperature Range: -45° to +250°F
Hardness: 50 to 80 durometers Shore A
Fluorocarbon (Viton)
When we talk about fluorocarbon O-rings, Viton is a popular trade name that may come into your mind. Fluorocarbon (FKM) compounds combine high-temperature resistance with excellent chemical resistance. These properties make them a popular choice for many applications, including aircraft and automotive industries.Resistant to: Petroleum base oils and fluids, some phosphate ester base fluids, silicone and silicate ester base lubricants, acids and halogenated hydrocarbons
Temperature Range: Standards -15°F to +400°F, but some Parker FKM Viton compounds can tolerate temperatures down to –65F and up to +450F.Hardness: 50-95 Durometers Shore A
Perfluoroelastomers (FFKM) (Parfluor)
Perfluoroelastomers (FFKM) are an extension of the Fluorocarbon FKM elastomers extending the compatibilities of the FKM while at the same time extending the upper temperature limits of the materials while compromising the lower temp limits. FFKMs are the cleanest/purest compounds available on the market. They are the first choice for clean applications and are particularly popular in the semiconductor industry.Silicone
Silicone O-rings have many outstanding properties, including excellent flexibility and fatigue life, strong ozone, and UV radiation resistance. Despite the abovementioned characteristics, experts do not recommend silicone O-rings for dynamic applications. The low strength and poor abrasion resistance as well as high gas permeability, make them not compatible with the most petroleum fluids, ketones, water, and steam.Resistant to: Dry heat (air to 400°F) and high aniline point oils
Not recommended for: Most petroleum fluids, ketones, water and steam
Temperature Range: -175F to +450°F
Hardness: 40-80 Durometers Shore A
Polytetrafluoroethylene (PTFE)
Polytetrafluoroethylene (PTFE) O-rings are designed to be used in harsh environments with temperatures ranging from -450°F to 600°F. PTFE O-rings are compatible with the widest range of chemicals, such as acetone, isopropyl, methyl, etc. Furthermore, they have low gas permeability and low absorption. Unfortunately, due to polytetrafluoroethylene material properties, pure PTFE O-rings are very rigid and hard to apply. Therefore, manufacturers, including Parker, solve this problem by mixing PTFE material with various fillers to provide users with more flexibility. PTFE seals are often used in food, pharmaceutical, and medical industries.Resistant to: Most chemicals, excluding alkali metals, fluorine, a few fluoro-chemicals such as chlorine tri-fluoride and oxygen difluoride
Not recommended for: Applications requiring O-Ring stretch and compression
Temperature Range: -260°F to 300°F
Hardness: 55 to 60 durometer Shore D
OH That makes it a lot easier But tks for the info.
Don’t use the “spray on” sun screen in the boat, it will pit up depth finder screens. Will look like water spots BUT it will not come off.
Would running Sea Foam regularly help/stop this problem or waste of $?
I use them to protect from sun screen/insect repellant (which are now banded from my boat) They will leave what looks like water spots but are actually pits on a Humminbird screen.
When I troll spinners or 3 ways I use a baitcaster. Someone on this site suggested the Okuma Low Profile Convector series for these applications as it has the flipping switch. That is what I will be upgrading to from my standard bait casters.
I have 4 of the Okuma Low Profile Convector series, used a lot last season for BB/long line trolling/snap weight trolling, no issues so far, way better drag than the Convectors used to have. I switched to dbl paddle handles from the power handles.
Not that I’m interested in making PFD’s mandatory however with the fit of the inflatables, I question the reason most people wouldn’t.
Totally agree! Tks for the post.
My issue searching atvs and sleds even is half of them are scams. I cant believe how many scams cl has these days

Couldn’t you just mount it on the end of a second bow mounted ulterra to auto stow / deploy and remote trim / pan? Let one ulterra control the boat and use the second one to steer and one to pan the transducer?Jesus, how much money do you guys have.
LOL
plan to fish Thursday and Friday to avoid the Saturday crowd.
If the weather is nice doesn’t matter what day it is. Have fun. Cedar Shore opened up & docks going in this week, that should help with the crowded ramps.
Scheels makes a 10′ 6″ Telescoping for around $100, I use them for lead core. Several brands make a 8′ 6″ for a lot less. I hate 2 piece rods!
That buggs the $hit out of me when guys do that, especially when they’re backing my vehicle down. Thanks for posting the video.

The other advantage is mice will not eat the spray foam so it seems to keep them out for the most part.
Ice castle use different spray foam than a boat? Don’t know if they eat it or not but mice will make a mess out of flotation spray foam.
Had a 2015, crew, 5.7, 100,000 mi, no major issues. Now have a 2019 (new body style) love this thing, especially the air ride!
In Panama City Beach Florida right now. 2 bdrm 2 bath condo on the beach 1/16/20 – 2/21/20 $2400 ($200 damage deposit refunded if ok) We have went to South Padre Island the past 4 years but wanted to try something different, miles from Omaha was the same. So far so good here.
“In August 2017, Camping World CEO Marcus Lemonis told supporters of President Donald Trump not to shop at his stores.”
And I won’t, thank you very much for the advice!
High water ramp at Snake Creek campground is open but has limited space for trailer parking.
I use size 27 Diawa’s. Spool 100′ of 14 lb braid (put a small piece of elect tape on the first wrap so it won’t slip) and then all 10 colors of 18lb superline leadcore (Tuf-line or Suffix super thin), must be the superline lead to get all 10 colors on. Small swivel and 10-12 lb mono or floro for leader. I usually make my leader the same length as my rod.

I’m close to cutting up my Cabelas Club card, which was once our primary CC# to use. We now use Amazon/Chase CC# and earn our bonus $$$ that way!
Much better in my opinionX2
