James walker P seals

This static seal is used in

casing and tubing heads

to seal rough casing and

production tubing. It is

energised by injection of

plastic packing sticks.

● Profiledsealing element of rubberised

fabric or homogeneous elastomer.

●Anti-extrusion elements comprise mesh

of compressed stainless steel wire.

● Wide rangeof top quality elastomer

and fabric materials suitable for oilfield

duties to meet customer specifications.

● Our P-Sealshave been tested in

accordance with API 6A specification.

In action, the inside diameter (primary

sealing face) acts on outside diameter of

the casing/tubing running through it. A

groove/recess in opposite face houses

injected plastic packing to energise the

system and create an effective seal.

P-Seals are supplied to suit standard API

casing/tubing sizes.

Plastic packing sticks

We make two grades for use with P-Seals

and other designs that are energised by

the injection of plastic packing.

● Standardtemperature packing sticks

(LR5640/C2 grade).

● Highertemperature packing sticks

(LRCM100B grade).

Both have thermally stable viscosity/flow

characteristics, together with low surface

friction and good surface adhesion.

Packing sticks are extruded in standard

diameters of 19mm to 38mm (¾ to 1½

inch). Other sizes supplied on request.
