Smaller diameter plugs can be used in all types of pipelines. Since these plugs are not reinforced with cord, they exhibit excellent stretching and sealing characteristics in pipe diameters from 20 mm (0.8″) up to 305 mm (12″).
Tire inflation valves may be removed to expose British Standard Pipe Thread fitting for direct hose connection or for adding a quick connect. Blocking plugs are 1/4" BSPT and bypass plugs are 1/8" BSPT excluding the 8”, 10” & 12” Bypass Plugs which are 1/4". By-pass plugs are threaded both ends.
