800 GoldEnd Tape Stops Leakage on Oxygen Gas Cylinders

Challenge

Background

Medical-grade oxygen gas is explosive and very hazardous. Gas cylinders are typically sealed with pure PTFE tape wrapped 5 – 8 times around the threads. Yet, the tape often shreds and tears, resulting in leaks and requiring special procedures to repair the leaking joint.

Solution

Product

Chesterton 800 GoldEnd® Tape is pure PTFE, ultra-high density, and meets Air Liquide (France) and BAM (German) certification for oxygen-safe sealing.

800 GoldEnd Tape requires only 1.5 – 2.5 wraps to get a leak-free seal.

800 GoldEnd Tape was chosen for its ability to resist tearing and shredding.

 

Results

Gas Joint Seal Improvements

Due to the fitting’s length and width, 0.75-inch wide 800 GoldEnd Tape was used to seal the joint. The depth of the “gas tight” threads required 2.5 wraps to fill the threads properly. Due to the ultra-high density of 800 GoldEnd Tape, one spool of 0.75 X 540 inches was sufficient to seal 50 gas cylinder valves compared to the 4 – 5 spools required of a typical PTFE tape. After sealing the cylinders, no leaks were observed throughout the operation.

800 GoldEnd Tape has been recognised as an industry standard for oxygen thread sealing.
