GT-11 - Griftan Fine Thread Cylinder Safety Cap 11-TPI

Essential Safety and Compliance for High-Pressure Cylinders

The Griftan Fine Thread Safety Cap (GT-11) is a critical safety accessory designed to ensure that your industrial gas cylinders meet the rigorous standards set by the Department of Transportation (DOT), OSHA, and MSHA. In any industrial or medical setting where high-pressure cylinders are utilized, the protection of the valve assembly is paramount. A sheared valve can turn a pressurized cylinder into a dangerous projectile, posing severe risks to personnel and property. This safety cap is engineered specifically to mitigate that risk, providing a robust physical barrier around the valve that absorbs impact in the event of a fall or collision.

One of the distinguishing features of the GT-11 is its compatibility with fine thread collars. While many older cylinders utilize coarse threads, a significant portion of modern high-pressure cylinders are manufactured with 11 threads per inch (TPI) on a 3-1/8 inch collar. It is vital to match the cap threading to the cylinder collar to ensure a secure fit; forcing a coarse thread cap onto a fine thread collar can strip the threads and compromise safety. This unit is precision-machined to thread smoothly onto 11 TPI collars, ensuring a tight and reliable connection that stays in place during transport and storage.

Beyond physical protection, this cap addresses the logistical challenges of cylinder transportation. DOT regulations require that the main valve be in the off position and adequately protected during transit. The Griftan safety cap fulfills this requirement, allowing you to transport cylinders legally and safely. Furthermore, the design incorporates a smart security feature: the standard lynch pin can be swapped out for a #3 Master Lock. This simple modification transforms the cap into a theft-deterrent device, preventing unauthorized access to the valve or the removal of the regulator, thereby securing your valuable equipment and gas supply.
