Product Description
Ring Joint Gaskets are precision machined metallic sealing rings,
suitable for high temperature and high pressure applications. By applying pressure to
the seal interface through bolt force, the softer metal of the gasket flflows into the
microfifine structure of the harder flflange material, creating a very tight and efficient
seal. They are available in several common profifiles to suit a variety of industry
standard flflanges.
Lone Star maintains API licenses 6A-0666, 0666.1, 0666.2 - Wellhead and

Style R Gaskets are manufactured in accordance with both API 6A and ASME B16.20 size/
ratings. Available in both oval and octagonal configurations, both types are interchangeable on
modern
Style RX are pressure energized adaptations of Style R gaskets, they are designed to fifit the same
groove design as a standard. The modified design has a pressure energized effect that improves the
efficiency of the seal as the internal pressure of the system increases.
Style SRX are ring gaskets based on the RX gasket design. They are designed with a special vent
hole drilled into it for use in Subsea applications. Style SRX gaskets are made in accordance with API
17D.
Style BX are pressure energized gaskets manufactured in accordance with API 6A and designed
for use up to 20,000 psi. All BX gaskets incorporate a pressure balance hole to ensure equalization of
pressure which may be trapped in the grooves.
Style SBX are ring gaskets based on the BX gasket design. They are designed with a special vent
hole drilled into it for underwater use. Style SBX gaskets are made in accordance with API 17D.
