About This Item
The Pentair Air Bleed Replacement Kit (WC8-126Z) is the OEM replacement air bleed assembly for Sta-Rite Posi-Flo II PTM Series cartridge filters and DEP Series D.E. filters.
⚠️ IMPORTANT: THIS LISTING IS A KIT — NOT A SINGLE COMPONENT
WC8-126Z is sold as a complete air bleed replacement kit. Confirm all included components are present before beginning service. Refer to your filter's parts diagram to verify this kit is the correct assembly for your model.
⚠️ IMPORTANT: VERIFY COMPATIBILITY BEFORE ORDERING
This kit is documented for Sta-Rite Posi-Flo II PTM Series models PTM50, PTM70, and PTM100, and Sta-Rite DEP Series models DEP36 and DEP36-1. Confirm your filter model number before ordering. Pentair catalog data for this part number was not available in the 2025–2026 extract — verify fitment against your filter's installation manual or the part number printed on your existing assembly.
The air bleed assembly allows trapped air to be purged from the filter tank, maintaining proper water flow and system pressure. A failed or degraded air bleed valve can prevent the filter from reaching operating pressure, cause erratic pressure gauge readings, or allow air locks to develop in the system. Replacing this kit restores correct venting function and sealing integrity to the filter's air relief point.

Pro Tip
Locate the part number stamped or molded on your existing air bleed assembly and match it to WC8-126Z before ordering. When servicing the air bleed, inspect the surrounding tank fitting and any associated O-rings for cracking or deformation — replacing these at the same time prevents a return trip to the equipment pad.
