- 270V Series - Blue 350 Deg Max
- Very High Temp - Single Hump
- With or Without SS Hose Clamps
Description
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 270V Series molded single hump exhaust bellows are made of Very High Temperature (VHT) Blue Silicone* blended with EPDM rubber with no textile reinforcement. This synthetic rubber blend is rated for use up to 350°F (177°C) max, continuous.
These bellows have excellent resistance to ozone, salt water, diesel fumes and splash, cold, heat, and aging.
Exceeds SAE J2006-R1 and ABYC & NMMA P-1 exhaust standards.
Available from 3" to 10" ID; with 5 step-up sizes also available; see Related Products.
Note – Part #s ending in SS come with (4) wide stainless T-bolt hose clamps.
• Blue silicone/EPDM blended rubber bellows - rated -65°F to +350°F maximum, continuous with a 10-year warranty
• Inlet/outlet cuffs are long enough to fit 2 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.
