Flange inside form has been finely standardized by us to make sure while torquing pressure on gasket which shows up as tightening torque comes as much earlier to gasket reaching flange thread start as possible.

Threads on flange are rolled.Form at thread start of flange prior to rolling has been standardized to yield a shape and configuration that results in minimal hooking.

Our rubber gasket compound formulation and process parameters have been standardized to yield high resilience.For a constant applied torque our gasket flows less into flange thread start and at same time has high resilience to spring out when torque taken off.

Our rubber gasket formulation and imparted physical properties allow enough pre-torque generation with plug gasket seat when inserted into plug that helps in extracting gasket out of flange thread whatever little it penetrates at the time of unscrewing the plug.

Our plug thread end towards gasket side has been standardized by feathering it out,not only does it increase tool life at time of thread rolling but also it fills crevices in flange thread start to restrict gasket entry into it.

Combination of our special plug geometry around gasket seat finely controlled and standardized,gasket dimensions and properties,flange inside curl shape yields flow path to gasket against applied torque that results in minimal gasket flow into flange thread start.
