Steel Rubber Gaskets

Designed to make and maintain a tighter seal than a standard rubber gasket.

Products

The G-S-S style WRAS approved Steel EPDM gasket with dimensions to BS EN 1514 is designed to make and maintain a tighter seal than a standard rubber gasket.

The Steel EPDM WRAS Gasket has a vulcanised steel ring for safe centring according to DIN EN 1514-1 PN6 – PN40, and tight sealing according to DIN EN 13555. The indication is that 15MPa is optimum gasket stress.

Advantages

Low stress sealing allows low torque requirements.
Owing to the versatility of the gasket material, it can be used on mis-matched or slightly misaligned flanges as the pressure is dispersed evenly.
The elastomers used have excellent energising properties that, if installed properly, maintain a tight seal regardless of fluctuating pressure and temperature.
The durability of the rubber offers a tight seal even on rough faced flanges and enamel coatings.

Technical

The torque values given are calculated to achieve 15MPa gasket stress and consideration is given to flanges from BS EN 1092-1 and BS EN 1092-2 along with the correct number and diameter of fasteners as per detail from BS EN 1092-1 Tables 11-15.

Material:	EPDM
Approvals:	WRAS, KTW, W270
Test basis:	DIN EN 681-1, ISO 9624
Temperature range:	-25°C to + 120°C
