Flexfab 7896-400, 4.00" ID 45° Silicone Elbow, Blue Coolant / Charge Air, 9.50" Legs

Turn a tight corner in your coolant or charge-air plumbing with the Flexfab 7896-400 45° silicone elbow. Its low-dilation, 3-ply meta-aramid construction holds shape under boost and heat — a dual-purpose elbow rated for both coolant hose and charge-air-connector duty.

Why this Flexfab 45° silicone elbow

• Dual-purpose design — works as a coolant hose or a charge-air connector, so one part covers two jobs.
• 3-ply meta-aramid, low-dilation — resists ballooning under pressure for a stable, reliable bend.
• −65°F to +500°F range — extreme-duty-cycle tested for hostile engine environments.
• Meets SAE J20 R1 Class A & TMC RP303B Class I Grade II — documented spec-grade performance.
• 4.00" (102mm) ID, 45° bend, 9.50" legs, .140"/.190" wall — sized for a clean clamp seal on both legs.

Pair with appropriate clamps on each leg for a secure, leak-free connection. Leg length is measured from the start of the bend radius to the end of the hose.

Backed by hpcouplers’ fast shipping and easy returns — order with confidence from a trusted industrial hose and coupler supplier.
