Product details

The CMP 25831-112-100 is a stainless steel piston shaft assembly built for the Pentair 7.5 in. P-Style slide valve body used on Triton and FNS Nautilus filter systems.

What it does

A slide valve directs water flow between filter and backwash positions, and the piston shaft is the internal rod that the valve handle moves back and forth to shift that flow path. The CMP 25831-112-100 is the internal piston shaft assembly for that valve, made of stainless steel.

Fit and compatibility

This assembly fits the Pentair 7.5 in. P-Style slide valve body used on Triton and FNS Nautilus filter systems, and it fits Pentair slide valve models 263064, 263053, 263052, 263078, and 263079. It replaces the Pentair OEM piston shaft assembly, part number 263055.

Before you order

Pentair slide valves come in more than one size and body style, so confirm your valve uses the 7.5 inch P-Style body before ordering. The CMP 25831-112-100 is sold individually as a single piston shaft assembly.
