This aluminum purge-gas retaining tape has an adhesive-free strip down the center of the tape to ensure adhesive doesn't contaminate the weld pool, creating high-quality welds. The tape seals the root gap to prevent purge gas from escaping during welding operations. Aluminum purge gas retaining tape withstands high temperatures up to 500° F and adheres to surfaces down to 10° F.

Aluminum purge gas-retaining tape has adhesive over the entire surface of the tape. The tape seals the root gap to prevent purge gas from escaping during welding operations. Aluminum purge gas retaining tape withstands high temperatures up to 500° F and adheres to surfaces down to 10° F.

Fiberglass weld-backing tape protects the backside of welds when surrounding oxygen in the pipe cannot be purged. This flexible tape conforms to uneven surfaces and creates a quality weld, speeding set up over welds that require gas purging. It has a fiberglass core running down the center and adhesive on both sides to cover the weld gap and secure the tap to the pipe. Applications include MIG, TIG, and SMAW (stick) welding.

Water-soluble tape holds water-soluble paper in place when used for gas purging. The tape dissolves with the paper when water or steam is introduced to the pipe after work is complete.
