Straight XHT Red Silicone Exhaust Bellows - 5" ID, Includes Clamps

Silicone 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.

Characteristics of the 272X Series of Bellows Exhaust Hose:
Glossy red extra high temperature, 100% silicone* rubber, which is reinforced with multiple plies of heat and fire resistant Nomex® fabric. Nomex reinforcing allows for higher pressure resistance for coolant, turbocharger, and other applications.
Single hump
Designed for wet exhaust & higher pressure critical water service.
Available from 2" to 12" inside diameter.

• 100% red silicone rubber bellows - rated -65°F to +500°F maximum, continuous duty, with a 10-year warranty
• Hand built
• Inlet/outlet cuffs are long enough to fit 2 hose clamps
• Note: Any part #s ending in SS come with 4 wide stainless T-bolt hose clamps


High Temperature Exhaust Hose Color Comparison
• Black exhaust hoses: made from molded, high temperature, black EPDM rubber. Rated -40°F to +250°F maximum continuous, with a 5-year warranty
• Blue exhaust hoses: made from a very high temperature, blue silicone rubber. Rated -65°F to +350°F maximum continuous, with a 10-year warranty
• Red exhaust hoses: made from an extra high temperature, red silicone rubber. Rated -65°F to +500°F maximum continuous, with a 10-year warranty

The addition of multi-ply fabric reinforcing enhances a hose's pressure resistance for coolant, turbocharger, and other higher pressure applications.


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