Caliper Piston – Stainless

316 Stainless Caliper Piston fits Al-ko and Trojan Calipers

316 stainless caliper piston fits Hydraulic Calipers made by Al-ko and Trojan. This great new product, made in our Brisbane workshops, will undoubtedly put the slide back into your pistons.

Stainless Pistons are precision machined from solid 316 stainless bar.

All Trojan calipers have phenolic pistons factory installed. This type of piston is subject to swelling, wear and tear.

However, Al-ko now has installed stainless calipers in both Dacromet and stainless disc calipers.

Sticky Pistons

For example, hydraulic oil and water is a corrosive mix. The movement of a phenolic piston creates small scouring marks, which, as a result, swells the phenolic piston.

The phenolic piston will become sticky and eventually fail, whereas the 316 Stainless will not absorb moisture and is therefore not subject to swelling.

Stainless pistons do not rust and help give a maintenance-free solution to hydraulic piston use.

You may like to consider stainless pistons in your stainless hydraulic caliper for improved performance.

Saltwater may enter the piston due to seal wear.

When installing, apply good lashing of hydraulic oil in the piston and around the seal inside the piston.

Cleaning Calipers

When tackling a caliper cleaning job, it is wise to have a new replacement seal kit ready if the old seals become stretched.

The sliding action of the stainless piston gives extended life over a standard piston.

Pro Tip: After installing a stainless piston in your Trojan calipers, empty all hydraulic lines of contaminated hydraulic fluid.

Finally, the quoted price is per piston.
