Metallic Gasket

The Ring Joint Gasket was initially developed for use in the petroleum industry, where high pressure/
temperature applications necessitated the need for a high integrity seal. They are mainly used in the oil
field on drilling and completion equipment. Ring Joint Gaskets are also commonly used on valves and
pipework assemblies, along with some high integrity pressure vessel joints.
The style R Ring Joint Gasket is manufactured in accordance with API 6A and ASME B16.20 to suit API 6B
and ASME B16.5 flanges.

R Style (Octagonal)
Standard ring joint gasket with octagonal Type cross section and designed for
flanges with standard ring joint grooves. Interchangeable with oval section gaskets
on modern octagonal grooved flanges.


R Style (Oval)
The oval ring gaskets have the greatest application of all ring gaskets used in industry
today. These gaskets fit API 6B and ASME B16.5 flanges. Oval type R gaskets fit all
current specification ring grooves, as well as "round bottom" ring grooves found in
some older flanges.

BX Style
Style BX gaskets incorporate a pressure balance hole to ensure equalization of
pressure which may be trapped in the grooves. Style BX pressure energized Ring
Type Joints, manufactured in accordance with API 6A, are designed for use on
pressurized systems up to 20000 psi. Although similar in style to the octagonal
gaskets, the BX Series can only be used with 6BX flanges and 16BX hubs. BXGaskets
have been designed for higher-pressure ratings starting at 5000 lbs. and
ending with 20000 lbs.

RX Style
Style RX is a pressure energized adaptation of the standard Style R Ring Type Joint.
As the RX is designed to fit the same groove design as a Standard Style R, the joints
are interchangeable. Style RX gaskets are designed for pressures up to 15000 psi.
These gaskets are interchangeable with R-oval or R-octagonal rings used on API 6B
flanges. Style RX is more costly than your standard oval or octagonal rings, therefore
not as popular. Style RX perform excellent in 6B flanged blowout preventer stacks,
which requires the additional mass of the RX to support the higher pressures with
higher vibrations and heavier weights of these units.
