Q: Are the NPT threads on this left hand threads? I need this exact piece but with the NPT left hand threaded
A: This fitting is a Right hand thread. We do not currently offer this part in a Left hand thread
Q: Can the 1/4" NPT side be unscrewed from the 1/4" MFL side then use the 1/4" MFL side to replace the hose barb on c384-t752hp?
A: The full valve would be the best option to replace, as unthreading just the barb could cause issues with the check valve on the inside of the shut off
Q: witch direction does the valve go ckeck valve ?
A: The flow goes from the NPT side of the Check Valve to the MFL side
Q: will this work for gas or methenal ?
A: As long as you are using the Check Valve with a CO2 regulator, it should work with Methanol
Q: This looks like a two part component. Is the check valve in the mfl portion, and does it have an o-ring like Taprite's hose barb fittings?
A: The MFL portion does contain the check valve, and it does have an o-ring which is accessible when you unscrew the MFL portion of the valve.
Q: Which way is the check valve flow? From the NPT to the flare or the other way?
A: The flow is from the NPT to the Flare. So co2 can pass through, but liquid can't pass the check valve.
