PPE 5.5" to 4.5" x 5" 5-Ply Silicone Reducer (Universal)

This PPE silicone reducer transitions from a 5.5" OD tube down to a 4.5" OD tube, measuring 5" long with 6mm 5-ply construction. It bridges two large pipe sizes in a charge-air or intake system.

The 5-ply reinforced silicone stands up to under-hood heat and boost, and its flexibility absorbs engine movement and vibration between the hard pipes it connects.

It is a universal part for large custom intake, intercooler or boost plumbing that needs to step between 5.5" and 4.5" tubing. Secure it with T-bolt or lined clamps (sold separately) for a boost-tight seal.

Sold individually, so order what you need and confirm both tube outside diameters (5.5" and 4.5") before ordering.
