Griftan Coarse Thread Cylinder Safety Cap 3-1/8 Inch

Heavy-Duty Valve Protection for the Shop Floor

Every welder knows that a falling cylinder is a potential torpedo if the valve shears off. The Griftan GT-7 Safety Cap is your first line of defense against this nightmare scenario. Built to withstand the rough and tumble environment of welding shops, construction sites, and fabrication yards, this cap screws securely onto your high-pressure tanks to armor the most vulnerable part of your gas setup. Whether you are moving tanks across the shop or loading them onto a truck for a job site, this cap ensures that a simple slip doesn't turn into a major safety incident.

This specific model is designed for cylinders with coarse threads—specifically 7 threads per inch on a 3-1/8 inch collar. It's crucial to check your tank's collar before ordering, as fine threads require a different cap. The coarse thread design allows for quick installation and removal, even when wearing heavy welding gloves. It spins on fast and locks down tight, giving you peace of mind that your oxygen, argon, or shielding gas cylinders are safe from impact damage. It meets all necessary DOT and OSHA requirements, so you won't get flagged during a safety inspection for having unprotected valves.

One of the standout features of this Griftan cap is its anti-theft capability. We all know that regulators and flowmeters have a habit of walking away on busy job sites. This cap features a clever design where the standard lynch pin can be swapped out for a #3 Master Lock. This allows you to lock the cap down, preventing unauthorized access to the valve and deterring theft of your expensive regulators. It’s a simple, practical solution that adds a layer of security to your valuable equipment without slowing down your workflow.
