Black Rubber Exhaust Bellows - 10" ID, w/o Clamps

Hump Hose Bellows provide flexible connectors for marine wet exhaust systems. They offer much greater tolerance to heat, misalignment, engine movement and vibration than rigid connectors, with significant savings in cost, parts, labor and space.

These THH Series molded hump exhaust bellows are 100% EPDM* rubber with no textile reinforcement. Available in 3" to 10" ID sizes.
Note: Any part #s ending in SS come with 4 wide stainless T-bolt hose clamps.

• Black bellows: made from molded, high temperature, black EPDM rubber. Rated -40°F to +250°F maximum, continuous duty, with a 5-year warranty
• Inlet/outlet cuffs are long enough to fit 2 hose clamps

*EPDM is Ethylene Propylene Diene Monomer, commonly referred to as EPDM or EPDM rubber. It can withstand relative high temperatures and exhibits excellent resistance to environmental factors such as Ozone, UV, acids, bases, and general weathering.
By comparison, Silicone rubber's outstanding characteristic is its resistance to even higher temperatures, as well as having a longer service life than EPDM. Silicone hose is compatible with water or anti-freeze such as coolant.
Neither of these synthetic rubbers is compatible with fuel or oil, so be careful to protect from exposure.
