Stuffing box packing AR (PAR)

Asbestos gland packing rolled rubberized AR (PAR)

It is used as a seal for stuffing boxes in hydraulic presses, steam hammers, centrifugal pumps, and as a lid gasket for autoclaves, steam boilers, etc.

When used correctly, due to the rolled structure, the packings of the AR and ARS brands can withstand higher pressure and have a higher wear resistance compared to the braided packings of the brands AP, AP-31, APR-31, AS and others, which allows an order of magnitude to increase the periods of non-stop operation of pumps. units of units, hydraulics, etc. Oil- and fuel-resistant.
