Frequently Asked Questions
Medium Pressure (MP) Cone & Thread Female connections are rated to 20,000 psi; High Pressure (HP) Cone & Thread Female connections extend to 60,000 psi. Both are available across connectors, unions, adapters, elbows, tees, crosses, hex nipples, caps, plugs, glands and collars.
The full range covers tube ODs from 1/4" to 1" across all six fitting categories, with consistent connection geometry regardless of size.
Yes. The SS 316 construction and precision cone & thread sealing used across this range is engineered for high-pressure hydrogen infrastructure, where material embrittlement and micro-leakage are the key risks.
