If not how can i tell what kind of threads i have? Thanks fellas. If it helps the guage is from an old regulator thats no longer made for airforce airguns. Its called an etac reg. Thanks.
There are 3 Main thread patterns in use. G1/8 BSP, 1/8 NPT and M10x1. British, American and Metric. All three are similar sized but with different thread patterns. I have put one into the other and got a leak free joint with enough thread sealant but it’s not recommended on out HPA equipment.
Don't know if you have a parkrose hardware store in your area or true value , but many of the nuts & bolt stores have gage boards so you can indentifie the thread size you need . Just a thought Darell
