Loc-Line 29451-BLK 1/4 Inline Check Valve Pack 10

This pack contains ten 1/4 inch acetal inline check valves designed for fluid control in plumbing and coolant circuits. Each valve permits flow in a single direction to prevent backflow. The acetal construction resists corrosion and chemical exposure. They suit technicians and builders who need reliable one-way flow management.

Consistent flow direction under continuous pressure

The check mechanism maintains its seal during sustained system operation without relying on external power. Acetal material stability ensures the internal components do not degrade quickly under constant fluid contact. This behaviour supports loops that run for extended periods without interruption. The valves respond immediately when flow stops or reverses.

Acetal body with standard 1/4 inch connections

The inline format fits directly into compatible tubing or piping runs without special tools. Black acetal bodies withstand typical workshop fluids and temperatures. Pack quantity of ten allows multiple installation points or spares for maintenance. Builders requiring different port sizes or metal housings will need alternative components.

Questions about this item

Does the 1/4" acetal inline check valve restrict flow or create back-pressure during continuous daily use?

The acetal body and inline design let fluid pass freely in one direction while preventing reverse flow, so normal daily operation adds no noticeable resistance.

What tubing or fittings must I already have to install the 1/4" Loc-Line check valves from the pack of 10?

You need 1/4" ID hose or tubing and matching barbed or push-to-connect fittings for each valve you plan to install.

Will these 1/4" acetal check valves work with the older 1/4" brass fittings I already own?

Yes, the 1/4" barb fits standard 1/4" ID hose used with legacy brass or plastic fittings, so they integrate without adapters.
