Product Details
Step cleanly between two pipe sizes with the Flexfab 7903-225250 silicone reducer. Its 4-ply meta-aramid construction handles the heat and boost pressure of coolant and charge-air systems alike — a dual-purpose reducer that holds shape and seals tight on both ends.
Why this Flexfab silicone reducer
-
Dual-purpose design — works as a coolant hose or a charge-air connector, so one reducer covers two jobs.
-
4-ply meta-aramid reinforcement — high pressure and temperature resistance for hostile engine environments.
-
−65°F to +500°F range — resists hardening, cracking, cold leaks, aging, and chemicals.
-
Meets SAE J20 R1 Class A & TMC RP303B Class I Grade II — documented spec-grade performance.
-
2.25" to 2.50" ID step, 6.00" OAL, .170"/.220" wall — sized for a clean clamp seal on each end.
Pair with appropriate clamps on each end for a secure, leak-free connection between mismatched pipe sizes.
Backed by hpcouplers’ fast shipping and easy returns — order with confidence from a trusted industrial hose and coupler supplier.
