High Pressure Cylinder Neck Ring 3-1/8-12 Fine Thread

Shop Safety Essentials: Cylinder Safety Collar Replacement

Every welder knows that a gas cylinder without a cap is a ticking time bomb. If a cylinder falls and the valve shears off, it becomes a torpedo capable of punching through brick walls. The High Pressure Safety Collar (3-1/8" x 12 Fine Thread) is your solution for cylinders that have damaged, stripped, or missing neck rings, ensuring you can always screw on a safety cap securely. Whether you are refurbishing older tanks or repairing a cylinder that took a bad hit, this replacement collar restores the safety functionality of your equipment.

This specific collar features a 3-1/8 inch diameter and utilizes a 12 TPI Fine Thread. It is crucial to match the thread pitch of your collar to your safety caps; fine threads provide a smooth, tight fit that stays put even when bouncing around in the back of a truck. The "Hybrid" designation often implies a versatile design meant to accommodate the rigorous needs of daily industrial use. By installing a fresh collar, you eliminate the frustration of fighting with cross-threaded caps or rusty rings that refuse to take a thread.

Maintaining your cylinder fleet isn't just about passing inspection; it's about keeping your shop and your crew safe. A damaged collar that won't accept a cap means that cylinder is grounded—you can't send it out for a refill, and you can't legally move it on the road. Keeping a spare AC-12 HYBRID collar on hand or using it to repair your current stock ensures that your workflow isn't interrupted by equipment that doesn't meet safety code. Rugged, reliable, and built for high-pressure applications, this collar is a small part that plays a huge role in your welding operations.
