An extremely pure graphite packing, Garlock GRAPH-LOCK products offer unmatched service in industrial environments where searing temperatures and crushing pressures cause constant failure of conventional packings.
It’s self-lubricating, dimensionally stable, impervious to gases and fluids, and corrosion resistant. GRAPH-LOCK products offer excellent sealing capabilities under extreme conditions for longer equipment life and less maintenance. It’s available in tape and die-formed rings from Garlock Compression Packing, and in sheet form from Garlock Sheet Products.
Garlock Compression Packing offers two purity levels of our GRAPH-LOCK products—commercial grade of 95% and nuclear grade of 99.5%. The nuclear grade material typically meets General Electric Spec. D50YP12, Rev. 2, dated Oct. 1992; MIL-P-24503B (SH); and can be certified for oxygen service.
GRAPH-LOCK DIAMOND TEXTURIZED TAPE
This diamond-texturized tape is an advanced and adaptable valve packing. Maintenance, tools, and downtime are cut considerably when installation or servicing is required. The tape is wound onto the stem and then compressed to half it’s width, repeated until the stuffing box is filled. Using this system, a small tape inventory can pack any size valve with superior sealing service.
