Cash-acme PPSV040808W-US Polypropylene Shut-off Valve 1/4 in

Product Description

The CASH-ACME PPSV040808W-US is a 1/4-inch polypropylene shut-off valve designed to provide reliable manual flow control in low-pressure fluid systems. Built from polypropylene, this valve resists corrosion and chemical degradation, making it well-suited for water filtration, RO (reverse osmosis), and other potable or process water applications. The quarter-turn design allows fast, positive shut-off without tools. Plumbers and water treatment technicians install this valve as part of supply line assemblies where a compact, lightweight shut-off point is required.

This valve is typically used in residential and light commercial water treatment installations, including under-sink filtration systems, ice maker lines, and similar 1/4-inch tubing circuits. Its polypropylene body keeps it compatible with treated and filtered water lines where metal fittings are not preferred. The compact form factor suits tight cabinet or under-sink spaces where clearance is limited.

Key Features

• 1/4-inch port size for direct integration into standard small-bore water lines
• Polypropylene construction resists corrosion and common water treatment chemicals
• Quarter-turn shut-off mechanism for fast, positive flow control
• Lightweight body reduces stress on tubing connections in tight installations
• Designed for potable water and filtration system applications

Compatibility

Designed as an OEM-style replacement or new-installation shut-off valve for 1/4-inch polypropylene tubing systems commonly found in residential water filtration and reverse osmosis setups.

Installation Notes

Installation should be performed by a licensed plumber or qualified water treatment technician in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before removing or installing any fitting. Avoid over-tightening connections on polypropylene fittings, as the material can crack under excessive torque. Verify the valve handle is in the closed position before restoring supply pressure.
