Hi! Thanks for sharing your detailed experience with our adapters and gauges.
Regarding the stability of the side adapters, they tend to secure more tightly above 50 bar. This is by design, as we primarily intended them for use on airgun cylinders and regulators, where pressures usually stay well above 50 bar during normal operation. However, we do acknowledge that with the Epoch's low-pressure gauge (under 50 bar), the situation is different, and we appreciate you pointing out the challenges you faced.
About using 1/8 BSPP threads in place of 1/8 NPT, especially in high-pressure applications, there are significant risks involved, including gas leakage, which can lead to safety issues. We always recommend using the correct, compatible thread types for each specific setup to ensure both safety and optimal performance.
Your suggestion about the adapters being adjustable to different positions is also noted. I've passed it on to our product development team for further consideration. If you have any other ideas or run into more issues, please don't hesitate to let us know. We're committed to improving our products based on user experiences like yours! THX!
