Extended range of aluminium pipe plugs

115mm diameters, so that pipes ranging in diameter from 40mm to 165mm can now be sealed. The plugs are manufactured using a new process, which ensures higher quality at the same price. The company was able to lower production costs to an extent that enabled the price rises of polymers (rubber seals) during recent months to be offset, allowing a stable price to be maintained and guaranteed. The plugs are normally supplied with a seal manufactured from natural rubber. For special uses, seals manufactured from various synthetic rubbers can also be supplied, such as nitrile rubber (NBR), chloroprene rubber (CR) and fluorine rubber (FPM). NBR guarantees high oil and petrol resistance, CR offers high ozone and atmospheric weathering protection, while FPM has proven to be extremely heat resistant. In certain cases, a longer threaded-hollow- shank is required, eg when a plug must be inserted further into a pipe, or when the placement of two seals on a shank is required in order to maintain greater pressure. A further advantage of the HFT aluminium plugs is the existence of a friction free washer made of synthetic material, which allows the plugs to be easily tightened by hand without the aid of additional tools, and makes damage or breakage of the wings nuts almost impossible.
