Griftan Fine Thread Cylinder Safety Cap 11-TPI

Rugged Valve Protection for Professional Welders

For welders and fabricators, gas cylinders are the lifeline of the trade, but they also represent a significant vulnerability if not handled correctly. The Griftan GT-11 Fine Thread Safety Cap is built to withstand the rough conditions of the job site, from the back of a welding rig to the corner of a busy shop. Designed specifically for cylinders with 11 threads per inch (Fine Thread), this cap screws securely onto standard 3-1/8 inch collars, providing armor for the most delicate part of your gas setup: the valve.

We know that equipment security is a major concern for mobile welders and shop owners alike. Regulators are expensive and prone to theft. The Griftan cap offers a practical solution to this problem. By replacing the included lynch pin with a standard #3 Master Lock, you can lock the cap in place. This prevents unauthorized users from tampering with your gas settings or stealing your regulator. It’s a small upgrade that adds a layer of security to your daily operations, giving you peace of mind when you leave your rig or shop unattended.

Functionality is key when you are swapping tanks or moving gear. This cap is designed to be user-friendly while meeting all necessary safety codes. Whether you are hauling oxygen, argon, or shielding gas mixes, if your cylinder has fine threads, this is the cap you need. It meets all MSHA, OSHA, and DOT requirements, ensuring you don't get flagged during a safety inspection. Don't risk a valve shear or a citation; equip your fleet with the proper fine-thread caps and keep your focus on the arc, not on the safety of your tanks.
