Manufactured To Your Exact Specifications

Key Gas Components has developed many special processes to fabricate custom manifolds to exacting tolerances in a cost-effective manner.

A special forming process is used to part and seal tubing or pipe in one operation. A special thermal drilling process extrudes holes through the tubing wall, extending the amount of material available for tapping. This allows us to achieve a higher quality pipe thread port that exceeds CSA requirements.

Robotic and other automated welding operations ensure consistently high-quality joining operations. As a final safety check, all gas manifold assemblies are 100% inspected for leakage prior to shipment.
