Super Flexmet XA

High Performance lead foil packing

Description:An exceptionally reliable, high performance, valve and pump packing. Constructed of lead foils that are treated with oil and graphite, then crinkled, twisted and folded round a core of graphite lubricated glass yarns to form a dense, strong packing. Lubricants are gradually released as the foil is deformed in the gland to ensure long and consistent service.

Typical applications: High speed rotary pumps and valves that handle steam, process water, brine, gasses, solvents or oil based products at relatively high temperatures. Also recommended for reciprocating compressors, especially on refrigeration plant.

Prime Features: Well proven for long operating life. Exceptionally reliable in high speed rotary pumps. Strong and easy to fit.

Chemical properties: Compatible with media in the range pH 4-10, including ammonia and many types of refrigerant.

How Supplied:All popular square sections from 3mm to 25mm, boxed in 4m spirals or coils. Also supplied as split preformed rings and sets. Full fitting instructions included.
