Product Description

The Parker C series check valve provides unidirectional control of liquids and gases. The valve body is made of stainless steel 316 for higher strength and greater corrosion resistance than stainless steel 304. Stainless steel 316 is sometimes called "marine-grade stainless steel" due to its resistance to chloride corrosion. This valve has A-Lok compression connections on both ends. With the Parker A-Lok design, the front and back ferrules secure the tubes within the fitting, creating a leak-proof connection without the need for additional joining preparations and methods such as flaring, soldering or welding. The cracking pressure is 0.33 pounds per square inch (psi), and the working temperature range is -15 to 400 degrees Fahrenheit.

Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. A ball cone valve utilizes a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines.

I needed a replacement for the OEM on my transmission cooler and this worked perfectly. This is probably overkill for this application but it installed super easy, looks great, & just plain worked.
