Wilwood Square O-Ring Seal Kit for Brake Calipers

Wilwood Square O-Ring Seal Kits, also called caliper square ring kits or caliper piston seal kits, are replacement seals for Wilwood brake calipers. Regular seal replacement helps prevent fluid leakage and keeps the pistons moving freely. This makes the kits useful for routine caliper maintenance and rebuilds.

Key Features:

• Square-ring seal design made for Wilwood caliper pistons
• Made from 210M seal material
• Helps hold hydraulic pressure and fluid inside the caliper
• Supports free piston travel and consistent braking response
• Offered in several configurations to suit different Wilwood caliper designs

Replacing worn or aging seals on a regular schedule helps keep your Wilwood calipers sealing and working reliably. This applies to street, strip and track use.
