About this part
What it is and why it is made that way
Seals are made in one shot with the correct hardness and elastomer grade — that is what makes a seal last. This line covers O-rings, gaskets and sealing rings in NBR, EPDM, silicone, Viton and PTFE-filled grades, moulded in the colour and Shore hardness your drawing specifies so a batch is traceable to the material used.
- Moulded in the specified elastomer grade and Shore hardness
- Elastomer batch traceable on request
- Coloured to specification, so a batch is visually identifiable
- Protective packaging so seals are not deformed in transit
