Flexfab 5415-238, 2.38" x 3 ft, 3-Ply Glossy Blue Silicone Coolant Hose, 60mm

Get a clean, durable seal in oil-splash engine environments with the Flexfab 5415-238 3-ply glossy silicone coolant hose. Its glossy lined exterior shrugs off oil, ozone, and UV, while the silicone core won’t harden, crack, or leak — so this 2.38" ID hose keeps performing where ordinary rubber breaks down.

Why this Flexfab glossy coolant hose

• Glossy oil-splash-resistant exterior — ideal for high-performance bays where oil mist is present, which means longer service life and a cleaner look.
• 3-ply polyester reinforcement — 210 PSI actual burst rating gives a wide margin over the ~70 PSI working pressure of most cooling systems.
• −65°F to +350°F range — stays flexible in cold and holds up to under-hood heat without going brittle or soft.
• Meets SAE J20 R1 Class A & TMC RP303B Class I Grade II — documented spec-grade performance.
• 2.38" (60mm) ID × 2.7" (69mm) OD, .140"/.190" wall — precise sizing for a leak-free clamp seal.

Supplied as a ready-to-install 3-foot stick, this hose pairs with a Flexfab 2582-0040 clamp for a connection that holds through repeated heat cycles.
