Stainless Steel Hydraulic Caliper Piston | Australian-Made

The Couplemate™ CM800 is a replacement Hydraulic Caliper Piston that suits both AL-KO Hydraulic Calipers and Trojan Hydraulic Calipers.

These stainless caliper pistons are made in our Australian warehouse. For improved performance, consider stainless pistons in your stainless hydraulic calliper.

Are Stainless Steel Pistons Worth it?

Phenolic caliper pistons are a common alternative to stainless steel. While they offer some resistance, they are incredibly susceptible to swelling, wear, and tear over time.

The movement of phenolic pistons creates slight abrasive marks, contributing to their gradual swelling and eventual adhesion, leading to failure.

In contrast, 316 Stainless Steel, renowned for its marine-grade quality and resistance to moisture absorption, provides a rust-free, low-maintenance solution when used in hydraulic pistons. The sliding mechanism of stainless pistons significantly prolongs their lifespan compared to standard counterparts.

For boat trailers using phenolic brake pistons, Couplemate™ engineers consistently recommend investing in our Australian-made Stainless Steel brake pistons for optimal performance and durability.

How to Install Replacement Caliper Pistons?

During installation, generously apply hydraulic oil on and around the seal within the piston. When acquiring new hydraulic calipers, owners have the option to purchase stainless pistons as an additional feature.

Seal wear might allow saltwater ingress into the piston, so it’s advisable to have a replacement seal kit on hand in case the old seals become stretched during caliper cleaning.

Pro Tip: After installing a stainless brake piston in Trojan calipers, flush all hydraulic lines to remove any contaminated fluid.
