These medical-grade Safety Check Valves are designed for air, or air/gas (non-liquid). We use them for a safety relief on the lids of our Wet Cell generators. They are made of Blue and Clear Polycarbonate with a Silicone Diaphragm. They have a cracking pressure of 0.142 psi. The entire check valve measures about 1/2" L x 1-1/8" D. Each end of the valve has two tiers (sockets) for .122" (3.1 mm) ID x .165" (4.2 mm) OD Tubing x 2. So, if using them with a hose application, the smallest tier measures approx. 1/16" OD , and approx. 1/4" OD for the larger step/tier. Commonly used in medical applications.

These are multi-purpose fittings and may possibly be used for Automotive, Boat (Marine), Hydroponic, Irrigation, Pneumatic, Agriculture, and Aquarium applications.

Please Note: These check valves are NOT High Flow check valves
