Use these CGA fittings to connect welding hose to pressure regulators and torches.

Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to harsh chemicals. They’re non-sagging, so they won't drip from vertical and overhead surfaces.

PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, remaining pliable enough to self-heal and stop leaks before they start.

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start.

Formulated to flow into small spaces, use these sealants between fine threads.

Completely free of oil and chemically inert, these sealants are safe to use with wet and dry oxygen systems.

Remaining pliable over time, these high-temperature sealants protect against leaks caused by vibration and pressure—they naturally fill voids before leaks can develop.
