HQPASFY Piston Shaft Assembly for Pentair Slide Valves — Replacement Kit (263064/263052) with O‑Rings & Lubricant

HQPASFY 263064, 263052 piston shaft assembly is a direct replacement piston-rod kit designed to restore smooth push-pull operation and reliable backwash switching on compatible Pentair slide and multi-port valves.

This piston shaft assembly rebuilds the internal push-pull mechanism in Pentair-style slide valves so your filtration system can switch cleanly between normal filtration and backwash cycles. Manufactured from wear-resistant plastic and supplied with rings and lubricant, the kit replaces several Pentair reference numbers and is intended as a drop-in service part for pool and spa valve maintenance.

How does this assembly control filtration and backwash modes?

The piston rod moves vertically inside the slide valve to change flow paths. Pulling the handle lifts the piston into the backwash position; pushing it down returns the unit to filtration. That movement isolates the cleaning flow and keeps water from bypassing the filter media.

• Push-pull piston action repositions internal valve ports.
• Precise fit reduces internal leakage and premature wear.
• Included O-rings and lubricant help maintain a tight seal.

What parts are included and what Pentair numbers does it replace?

The kit ships complete with the piston shaft assembly, a black round cover, lubricant sachet, two small O-rings and one large O-ring for sealing. It is cross-referenced to multiple Pentair replacement numbers so you can match it to your valve.

• Complete piston rod assembly for immediate installation.
• Sealing hardware (2 small O-rings, 1 large O-ring) to prevent leaks.
• Lubricant to ease installation and protect seals from wear.
• Compatible with Pentair numbers 263055, 263064, 263052, 263053, 263078, 263079.

How simple is installation and what safety steps should I take?

Installing the piston shaft assembly is straightforward for anyone comfortable with basic pool maintenance. Always power down the pump and relieve system pressure before disassembling the valve to avoid water discharge and injury.

• Turn off equipment and depressurize the filtration system first.
• Remove the valve cover and extract the old piston rod carefully.
• Fit the supplied O-rings and apply the included lubricant for a smooth seal.
• Reassemble, restore pressure, and cycle the valve to confirm function.

What material qualities ensure long service life?

The main components are molded from durable plastic chosen for corrosion resistance and tolerance to pool chemicals and temperature fluctuations. Robust material and correct sealing reduce friction and the risk of cracking from repeated valve operation.

• Corrosion-resistant plastic body for extended field life.
• Heat and wear tolerant to withstand frequent use.
• Precision-molded contact surfaces reduce abrasion on the slide valve.

Who this is for: Pool and spa owners, service technicians, and maintenance professionals who need an affordable, OEM-compatible piston rod replacement for Pentair-style slide or multi-port valves. If you’re troubleshooting valve leaks, sticky backwash operation, or degraded sealing, this kit provides the parts and basic hardware to restore dependable switching between filtration and cleaning cycles.
