Pump Pulley Flange Fits 05-1337

The Peterson Fluid Pump Pulley Flange Fits 05-1637 is a press-fit pulley flange engineered for use with 1 or 1-1/2 inch wide pulleys in high-performance engine applications. This aluminum component features black anodized finishing to provide corrosion resistance and durability in demanding under-hood environments where coolant flow management is critical.

Constructed from aluminum and finished with black anodized coating, this flange is designed to interface directly with Peterson's precision pulley systems. The press-fit design ensures secure mounting without additional fasteners, simplifying installation while maintaining concentricity essential for balanced pulley operation. The compact dimensions (4.85 x 0.5 x 5.4 inches) and lightweight construction (0.06 lbs) make this component ideal for custom cooling systems where weight savings and space constraints matter. The anodized surface resists oxidation and chemical degradation from coolant exposure, extending service life in both street and racing applications.

This pulley flange is intended for builders and technicians assembling or upgrading engine cooling systems with Peterson fluid management components. Whether you're configuring a street performance engine, vintage restoration project, or dedicated race platform, this flange provides the interface needed to integrate multiple pulleys into a cohesive belt-drive system. Proper pulley alignment and flange fitment directly affect belt wear rates and thermal efficiency—this component ensures precise alignment within Peterson's ecosystem.

Peterson Fluid Systems is recognized for manufacturing precision cooling components that meet the demands of both production and competition-level powerplants. This flange represents the engineering standard Peterson applies across its pulley lineup, ensuring compatibility and reliability when sourcing components as a complete system rather than mixing brands.
