What Mounting Thread sizes are available?

We offer a wide range of industry-standard mounting threads to ensure compatibility with existing equipment. Common bulkhead thread sizes include 7/16-20 UNF (for Micro series), 1/2-20 UNF, and 5/8-18 UNF (for Standard series). We can also machine custom Metric (e.g., M10, M12) or NPT threads upon request.

Seamless integration is our goal.

Micro Series: Typically uses 7/16-20 UNF.
Standard/L-Type Series: Often uses 7/16-20 UNF (for 2-5 pins) or 5/8-18 UNF (for 6-12 pins) and 1-14 UNS for high-power versions.
Customization: Because we manufacture our own shells using CNC machining, we can modify the thread length (shank length) or type to fit thick pressure hulls or specific sensor housings without requiring an adapter.
