Pikotek HCS firesafe washers

As part of the development of the VCFS Firesafe gasket we had to overcome the potential of the loss of bolt load during the burn process of the API 6FB test. Therefore we developed the new X37 hardened coated steel washer system that withstood those demands.

Now Pikotek are pleased to offer the X37 washers for all our isolating kits which mitigates the potential of washer damage under excessive torque value. Coupled with removing the ability to fit the washers incorrectly thereby causing the possible loss of isolation properties this new development will make the Pikotek Isolation Kit the most secure option for your needs.
