HTMS is experienced in designing and manufacturing resilient metal seals for extreme environmental service conditions. HTMS metal seals, O-Rings, C-Rings, Spring Energised C-Rings and Spring Energised O-Rings are produced from high quality alloy materials with full lot control, full traceability and inspection procedures at all production steps.

All production procedures starting from purchase to shipment are controlled by our Q.A. manual. HTMS is an ISO 9001 certified manufacturer of resilient metal seals. Regular internal audits verify that work procedures are maintained and compliant with our Q.A. manual.

HTMS works closely with its customers to analyse sealing problems as correctly as possible and, based on application data, to design and manufacture the best seal for the given application.

We strive to manufacture only correct products and are confident that our seals will be free of all material or manufacturing defects. Should a mistake be made we will replace any defective products with the highest priority free of charge.

Our warranty is limited to the replacement value of the defective seals only and does not include any additional or consequential liabilities.

Resilient metal seals are sensitive seals by design. Nevertheless, depending on the performance requirements, other parameters, such as handling, effective groove sizes and surface roughness, are equally important to achieve the desired results.

The seal being only one part of the sealing solution, HTMS cannot guarantee any leak rate, nor can we accept any liability for costs following poor sealing results. However, should the problem be related to faulty parts, HTMS will replace the parts free of charge.

Except for the general recommendations found in this design manual, we cannot give specific warranties for life expectancy, leak rate or other operational parameters. Customers are always advised to qualify seals, preferably by real life testing, or by similarity, in the exact configuration of their intended use.
