Aluminium Expanding Pipe Stoppers 1.5″ to 24″

Pipe stoppers, also known as drain plugs, are designed to temporarily seal pipe ends or openings for various testing applications. These devices primarily seal pipes from water, gases, and foreign objects in newly installed pipework or systems undergoing repair.

Multiple styles are available to accommodate different applications, with pipe sizes ranging from 1/2″ to 24″. Specialised pipe stoppers for pressure testing are also available, with sizes extending up to 24″ (609.6 mm).

The stopper features a central spindle or shaft fitted with two plates and a natural rubber tire (ring) positioned between them. A wing nut on the shaft moves the plates together, compressing the tire to create a seal within the pipe. These stoppers can be supplied with hollow shaft versions for standard hose connections or for use with fixed or free nipple caps.

Complete size ranges of aluminium plugs are offered, starting from 1.5″ and suitable for demanding applications including chemical immersion and elevated temperature conditions.

Expandable plugs are manufactured in nylon and steel materials as alternatives to aluminium.

All plugs meet British Standards BS8005 requirements for low pressure testing and pipe sealing applications.
