Designed with a groove seat to hold the O-ring in place during connection. The O-ring seal is placed on the O-ring groove seat and compressed during the bolt tightening process.

The tightening of bolts pulls the flat side and O-ring side together to form a seal.
Annular (circumferential) tool marks up to a surface irregular roughness value of ISO 1302-MRR Ramax 3.2 µm are acceptable.
Apply in high-temperature installation
Suitable to apply in both high and low temperatures.
A rubber O-ring material made from Buna 90 shore (NBR) and Viton 90 shore is used to connect two surfaces.
It is made of a rubber material and is mostly used to seal two working surfaces.

Leak Free Connection
One of the major strengths of the O-ring side is the reduction of leakages it gives during connection.
Most times, metal to metal flanges when connected have a high risk of leakage. However, with the O-ring placed in-between the flange, there is less friction and risk of leakage is reduced too.
