Pentair 1/4" x 1/4" Tube Check Valve | R172323
The Pentair 1/4″ x 1/4″ Tube Check Valve (R172323) is a compact one-way flow valve designed for use in pool and spa systems where small-diameter tubing is used. This check valve allows fluid or air to flow in one direction only, preventing backflow and helping maintain proper system operation in chemical feeders, automation, pressure lines, and other applications that require controlled directional flow.
What This Part Is For
This check valve is used with 1/4" diameter tubing commonly found in automatic chemical feed systems, vacuum switches, heaters, controllers, and other pool/spa devices where one-way flow must be maintained. It prevents undesirable backflow that could affect performance or cause contamination of upstream components.
Features & Benefits
- Designed for 1/4" tube connections — no adapters required for correct size
- One-way flow design prevents backflow for more reliable operation
- Compact, inline construction for easy installation in tight spaces
- Compatible with common pool and spa tubing applications
Installation Notes
- Confirm proper flow direction — arrow on the valve must point downstream
- Cut tubing squarely before inserting into check valve ends
- Push tubing fully into valve fittings to ensure a secure seal
- Use clamps if recommended for your tubing type to prevent slippage
Maintenance Tips
- Inspect periodically for cracking, debris, or loss of one-way function
- Replace if flow becomes restricted or backflow occurs
- Keep adjacent tubing and components clean to support proper valve function
