Expansion Bag Plugs for FME Applications
For when the job demands dependable pipe isolation, foreign material exclusion (FME), or very low-pressure gas testing. The Expansion Bag Plugs range at HTC delivers industrial-grade performance trusted by gas utility technicians, contractors, and specialized safety teams.
- Designed for flexibility, durability, and a snug fit. These multi-size inflatable bag plugs consist of an inner high-quality Natural Rubber bladder encased in a protective 100% Polyester fabric cover.
- This allows them to exhibit excellent sealing and good shut-off characteristics across variable pipeline diameters where a plain rubber bag would not hold.
- They feature an expertly crafted construction where the gauge of the rubber and polyester varies with the size of the bag, a dependable inflation valve interface, and a rugged friction-resistant exterior canvas to simplify manipulation. Perfect for gas infrastructure networks, this specialized range is also compatible with dedicated low-pressure monitoring gauges for demanding pipeline maintenance applications.

Engineered for FME Applications and Very Low Pressure Gas Testing
The expansion bag plug range from HTC. This is engineered to deliver reliable sealing, isolation, and testing for pipelines where clearance is tight. Or shapes are out-of-round, or traditional mechanical plugs are too rigid or heavy. From small-diameter utility pipes to massive industrial headers, these bladders compress cleanly. This allows for easy deployment and expand uniformly to ensure a positive shut-off.
