Ring Joint Gasket

Product Description

Stoplik Metallic Ring Joint Gaskets are heavy duly, high-pressure gaskets largely used in offshore petrochemical and natural gas industry applications. They are precision-engineered components designed to be used in conjunction with precisionmachined flanges. The Gaskets are available in R, RX, BX styles and in oval/octagonal profiles. Stoplik manufactures gaskets in accordance with specific tolerances on CNC machines. All our Ring Joints are manufactured according to ASME B16.20 – API Std 6A BS EN 12560-5

Properties And Application

The metallic ring joint gaskets are manufactured according to the API 6 and ASME B16.20 standards for application at elevated temperatures and pressures. The small sealing area with high contact pressure results in great reliability. The contact surfaces of the gaskets and flange should be carefully processed. Some types of ring-joints are pressure activated, that is , the greater the pressure the better the sealability.

Shape And Construction

Stoplik Style 9000 Ring Joint Gasket

Our ring joint gaskets are machined from solid metal in a variety of shapes with high quality numerical control machines. They are designed for high pressure, high temperature or highly corrosive appications by selecting the most suitable materials and shapes.

Stoplik Style 9000 R Type Oval Ring Joint Gasket

A stansdard ring joint gasket with oval cross section and designed for flanges with standard ring joint grooves.

Stoplik Style 9000 R Type Octagonal Ring Joint Gasket
