Types of RTJ Gaskets Offered

We offer a wide range of ring joint gaskets in Singapore.R-Type: Commonly utilized in the petrochemical industry, an R-type gasket is a basic ring joint gasket in the Singapore market. We offer R-type RTJ gaskets in two classifications: oval and octagonal. The oval R-Type RTJ gasket is the original design while the octagonal counterpart is an alteration to the former. The octagonal R-type RTJ gasket is ideal if you are looking for a gasket that delivers better sealing properties.


Recommended Service Conditions for R-Type RTJ Gaskets

RX-Type: An RX-type RTJ gasket is constructed in such a way that it can be interchanged with an R-type RTJ gasket. When interchanged, it actually delivers a better sealing performance. That’s because compared to an R-type RTJ gasket, an RX- type is wider, which means its flange face-to-face separation is tighter. Due to its superb sealing attributes, it is widely used by operators who want utmost protection against unnecessary and prolonged shock loadings and vibrations.

BX Type: A BX-type RTJ gasket is known for its internal system pressure which is specifically designed to increase seating stress on flange contact surfaces. It is a cut above the rest when it comes to sealing surfaces since it is the only RTJ gasket that is suitable for API-type BX flanges and grooves.
