can you push gas (oxygen) through this? What is minimum pressure requirement?
Q can you push gas (oxygen) through this? What is minimum pressure requirement?A It is possible and some customers have used fittings like this in the past. The tri-clamp fittings are leakproof and cracking pressures, dependent upon the size of the valve, are located lower down on this page.
For the 1.5" tri-clamp. What size and type of gasket is used to join the two halves?
Q For the 1.5" tri-clamp. What size and type of gasket is used to join the two halves?A Our sanitary fitting sizes are universal. So for the 1 1/2" Tri-Clamp Fittings, you would choose the 1 1/2" Tri-Clamp Gasket size.

Are these check valves suitable for both vertical and horizontal installations?
Q Are these check valves suitable for both vertical and horizontal installations?A Yes, these tri-clamp check valves can be used in both vertical and horizontal installations. Please verify cracking pressure along with liquid weight which will impact the opening of check valve.
What is the largest OD of the valve with the clamp used in the center?
Q What is the largest OD of the valve with the clamp used in the center?A I'm not sure if I understand your question correctly, but the largest outside diameter tri clamp check valve that we offer is 6". Please call or email for additional information.
What material is the green O-ring gasket in the check valve?
