Flexfab 7903-100150, 1.00" to 1.50" ID Silicone Reducer, Blue Coolant / Charge Air, 6.00" OAL

Product Details

Step cleanly between two pipe sizes with the Flexfab 7903-100150 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.
• 1.00" to 1.50" 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.
