Type VR2 Expanded Graphite Gland Packing

Type VR2 Die-Formed is produced by compressing an exact amount of Grafan Ribbon Tape in precision metal moulds. The result gives uniform quality, dense, smooth finished, close tolerance, die-formed rings. A large range of Grafan rings are available ex-stock. Any custom size or shape can be produced, usually from existing tooling with a range of densities available from 0.578 to 0.0723 oz/cu in (1 to 1/8 g/cm3). VR2 die-formed rings are supplied just to size for ease of fitting. When energised in the gland, the rings compress to effect a perfect leak-free seal on valves. It
is well proven that valves packed with these materials have been in service for years, leak free without maintenance, where previous braided packing have failed within weeks or months.

Type VR2 standard spool length is 8 metres. Custom lengths can be available - please contact us using the form.

Applications: Extreme condition, long life and zero leakage packing for all uses, up to high temperature, high-pressure, high-speed applications on pumps, valves, mixers, agitators, expansion joints, ball valve seats and other static seals. Types VR1 and VR31 are designed for use in static applications only. Against all acids, alkalis and solvents (except very strong oxidants), gases, feed water and superheated, or saturated steam.
