A consecutive series of convolutions that can be compressed at an average of 2:1 along its length. Popular for breathing, boot, and sleeve/cover applications. Can be made in I.D.'s from 3/8" to 3".
Helical convolutions that can be compressed at an average of 2:1 along its length. Popular for breathing, air intake, drain, vacuum, and sleeve/cover applications. Can be made in I.D.'s from 3/8" to 3".
A consecutive series of convolutions that can be stretched up to 4:1 along its length. The amount of stretch varies with the wall thickness used. Popular for bellows and farm equipment applications, but has many uses. Can be made in I.D.'s from 3/8" to 3".
Helical convolutions that can be stretched up to 4:1 along its length. The amount of stretch varies with the wall thickness used. Popular for farm equipment, drain, vacuum, and air intake applications, just to name a few. Can be made in I.D.'s from 3/8" to 3".
Our heavy-duty line. They are a very rugged version of a spiral spaced tube and are offered in fixed length and compressible formats. I.D.'s range from 1" to 6" with almost any dimension in between being possible. Typically .1" is the minimum wall thickness available.
EPDM is, in simple terms, a mule. It rates well for most applications, is the best or worst for very few, and is very cost effective. Because of its versatility and cost effective nature, it is by far our most commonly specified compound. It has outstanding resistance to aging, weathering, ozone, oxygen and many chemicals. It’s high and low temperature stability as well as steam and water resistance is excellent. EPDM applications include:
- Breathing hoses
- Garage exhaust hoses
- Boots and bellows
- Vacuum hose
- Seed tubes
- Drain hoses
- Air intake hoses
Available in 60 and 75 Shore A durometer.
Available in a Flame-Retardant version.
Available in any color imaginable (may be significantly more expensive; order minimums will be higher)
NOTE: Should not be used if frequent contact with petroleum based fluids is expected.
Butyl rubber has exceptionally low gas and moisture permeability and outstanding resistance to heat aging, ozone, chemical attack, flexing, abrasion and tearing. It has good resistance to phosphate ester based hydraulic fluids, and has excellent electrical insulation performance. Butyl is not recommended for use when in contact with petroleum oils and fluids. It is most popular with military and first-responder equipment manufacturers, and suitable applications include:
- Breathing Hoses (primarily for chemical attack applications)
- Drain Hoses
- Ducting/Air Intake Hoses
- Transfer Hoses (primarily for chemical attack applications)
Nitrile provides excellent resistance to petroleum-based oils and gasoline as well as mineral and vegetable oils. Another main advantage of Nitrile is that it is non-conductive. However, Nitrile has poor resistance to the swelling action of oxygenated solvents such as acetone and ketones. It has good resistance to acids and bases except those having strong oxidizing effects. Suitable applications include:
- Containment boots
- Boots and bellows (primarily when subjected to oil)
- Breathing tubes requiring oil resistance
Neoprene polychloroprene was the world's first synthetic elastomer with oil resistance and is still the primary choice in a number of applications, including automotive and construction. In the automotive world, Neoprene remains the choice for many underhood and underbody parts that require a mid-performance polymer with a good all-around balance of performance properties. It can be used in a wide variety of applications, but because of its cost relative to EPDM, it is seldom used unless specifically requested. We are happy to run it and typically have it in-stock.
Specialty: Flame retardant, high-temp, low-temp, colors, and many more options are available. Please tell us about your application and we'll find a solution!
