When the bolted connection is tightened, the sealing lip is pressed against the flat surfaces. The metal washer ensures that the components to be con-nected are reliably and securely held. The thickness of the washer limits the compression of the elastomer seal, eliminates any over torque of the joint, thereby ensuring a reliable sealing system. The internal pressure increases the sealing force by energising the sealing lip.

GM1000 Sealing Ring
- Good sealing function with a low tightening moment - No need of a countersink to center 
the seal, this is achieved thanks to the design of the sealing lip
- Mostly used together with metric bolts with hexagonal  headsasper DIN specification
- On request GM 1000 can also be made for inch  threadsaswellasfor specialbolt



GM2000 Sealing Ring
- Rubber to metal bonded seal with specially designed sealing lip for threads and nuts
- No need of a countersink to center the seal, this is achieved thanks to the design of the sealing lip
- The seal prevents leakage by sealing in the thread 
- The three contact lips of the rubber body seal the thread to nut and machine component
- Positively retained
- Mostly used together with hexagonal nuts as per DIN specification as well as for threaded connectors and adjusting screws

KDS Sealing Ring
- Rubber and metal bondeding, EO-3 soft sealing ring for Banjo Fitting.
- EO-3 is an innovative Parker flareless fitting for metric tubing similar to the EO and EO-2 series.
The EO3 flareless fitting system utilizes a visual indicator to prevent leakage due to inadequate 
or over-tightening, allowing the user more control to make high-quality, fast connections.

The style of the BonDED SEAL is as follows:

Bonded seals are available in a choice of materials including :
