RSP Group's Ring Joint Gaskets are manufactured in accordance with API-6A and ASME B16.20 specifications and come in four basic types :

•    R(Oval Type) Ring Joint Gaskets
•    R(Octagonal Type) Ring Joint Gaskets
•    RX Style Ring Joint Gaskets
•    BX Style Ring Joint Gaskets

These basic shapes of the Ring Joint Gaskets are used in a variety of applications with pressures up to 20,000 PSI. The dimensions are standardized and require specially grooved flanges by where a corresponding "R" or "BX" number is assigned for pipe size and pressure class for gasket identification.

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 octagonal type grooved flanges.

Style R Ring Joint gaskets can be manufactured in accordance with all relevant standards to suit the following flange designations: API- 6A, ASME/ANSI B16.5, MSS SP44 (ASME B 16.47 Series A) & BS 1560.

Toleraces (Inches):
+ Width of Ring: ±0.008
+ Height of Ring: ±0.020
+ Pitch Diameter: ±0.007
+ (Octagonal) Angle of 23°: ±0.5°

Style RX is a pressure-energized adaptation of the standard Style R gasket. The RX is designed to fit the same groove design as a standard Style R, making the joints interchangeable. The modified design uses a pressure-energized effect that improves the efficiency of the seal as the internal pressure of the system increases.

Toleraces (Inches):
+ Width of Ring: +0.008,-0.000
+ Height of Ring: +0.008,-0.000
+ OD of Ring: +0.002,-0.000
+ Angle of 23°: ±0.5°

Style BX pressure energized Ring Joint Gaskets are manufactured in accordance with API 6A and are designed for use on pressurized systems up to 20,000 PSI.

When correctly fitted, the style BX Ring Joint Gasket allows virtual surface-to-surface contact of the flange faces, which means that the Ring Joint Gasket is fully trapped on both the inner and outer diameters.

All BX Ring Joint Gasket incorporate a pressure balance hole to ensure equalization of pressure that may be trapped in the grooves.

Toleraces (Inches):
+ Width of Ring: +0.008,-0.000
+ Height of Ring: +0.008,-0.000
+ OD of Ring: +0.000,-0.006
+ Angle of 23°: ±0.25°
+ Hole Size: ±0.02
