1/4" Barb Polypropylene Check Valve
This 1/4-inch barb check valve uses a polypropylene body with an inline ball-cone mechanism. Buna-N seals handle fluids between minus 20 and 140 degrees Fahrenheit. It suits horizontal or vertical mounting in low-pressure water or air lines. Buyers needing metal construction or higher temperature ratings should choose a different valve.
Pressure and orientation limits
The valve cracks open at 1.0 psi and withstands up to 125 psi maximum water pressure. Operation is rated from minus 20 to 140 degrees Fahrenheit in either horizontal or vertical orientation. Systems that exceed 125 psi or require a higher cracking pressure will not be served by this part.
1/4-inch barb connection
The defining specification is the 1/4-inch barb-by-barb connection that matches soft tubing of the same inside diameter. If your tubing or pipe uses a different size or thread type, this valve will not fit without adapters.

Questions about this item
Is the 1/4 inch barb size the right choice for my tubing?
The valve uses a 1/4 inch barb connection on both ends, so match it to tubing with the same inside diameter for a secure fit.
What does the 1.0 psi cracking pressure mean for flow?
The valve begins to open at 1.0 psi, allowing flow in one direction while preventing backflow below that pressure.
Will the barb connections handle my system pressure?
The valve is rated for a maximum water pressure of 125 psi, which the barb connections are designed to withstand.
