RTJ Gaskets
RTJ Gaskets / R-Series
The R-Type ring gasket can be ordered to two different profiles, oval or octagonal in cross-sections. Both types have identical pitch diameter as the flange groove they correspond to. These gaskets are used in pressures up to 5,000 PSI. The octagonal type has a higher sealing coeffient than the oval, therefore being the better gasket of the two. The oval type is the only gasket that will fit a bottom radiused groove. Flanges with flat bottom v-grooves will accept either style. Gaskets that have been torqued initiating a metal-to-metal seal should be discarded and not reused.
RTJ Gaskets / RX-Series
RX gaskets are designed for pressures up to 5,000 PSI. These gaskets are interchangeable with R-oval or R-octagonal rings used on API 6B flanges. RX types of gaskets are more costly than your standard oval or octagonal rings, therefore not as popular. RX type gaskets perform excellent in 6B flanged blowout preventer stacks, which requires the additional mass of the RX gasket to support the higher pressures with higher vibrations and heavier weights of these units. Gaskets that have been torqued initiating a metal-to-metal seal should be discarded and not reused.
RTJ Gaskets / BX-Series
Although similar in style to the octagonal gaskets, the BX Series can only be used with 6BX flanges and 16BX hubs. BX-Gaskets have been designed for higher-pressure ratings starting at 5,000 lbs. and ending with 20,000 lbs. Pitch diameters on BX gaskets are slightly larger than the pitch diameter of the flange. This forces the gasket to initially seal on its outside angles and secondly seal with its inside angles as the flange is bolted down to respective torque settings. Gaskets that have been torqued initiating a metal-to-metal seal should be discarded and not reused.
Gaskets coin themselves (Blend In / Molds) to the surface finish of the groove, forming a custom surface seal. The vent hole on the BX Series through the gasket helps equalize pressures caught between the flange grooves. Gaskets that have been torqued initiating a metal-to-metal seal should be discarded and not reused.
RTJ Gaskets / SRX & SBX Series
The American Petroleum has standardized the underwater utilization of ring gaskets with the SRX and the SBX series rings. There is no dimensional difference between the standard RX and SRX or the BX and SBX. They will fit into their appropriate flange designated numbers. The "S" prefix identifies a gasket as having intersecting vent holes, allowing a pressure less metal-to-metal initial contact between the gasket and flange groove, while made up underwater. For pressure class ratings on these gaskets refer back to their non "S" type standard gasket classification chart for the RX-Series and BX-Series. Gaskets that have been torqued initiating a metal-to-metal seal should be discarded and not reused.
Pressure Class Ratings
RTJ Gaskets / Rubber Coated Series
Rubber coated gaskets start with a precision machined low carbon steel gasket. We then add rubber which gets moulded to the gasket in an electrically induced 300 ton compression press in our own manufacturing plant. These gaskets are used in hydrostatic testing of equipment where testing pressures can exceed more than two times the equipment's normal operating range.
With proper care, these gaskets can be reused numerous times. They also help to minimize and prevent additional damage to a flange groove.
We recommend storing these gaskets away from excessive heat and ultraviolet light. Shelf life is contingent on storage conditions but gaskets should remain useable for a minimum of 5 years.

RTJ Gaskets / OEM Gaskets
TXG uses a computerized CMM (Coordinate Measuring Machine) to inspect and deliver inspection reports for your OEM gaskets. TXG holds extensive manufacturing equipment and raw material stock supplied from quality cautious vendors.
Valve, wellhead and subsea gaskets can be manufactured in any material and coating combination. We can reverse engineer used gaskets to ensure obsolete or otherwise unidentified connections have a proper seal.
