HTMS is experienced in the design and manufacture of resilient metal seals for extreme environmental service conditions. HTMS metal seals, O-Rings, C-Rings, spring energised C Rings and 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 certifi ed 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 their customers to analyse as correct as possible the sealing problem and based on this application data, design and manufacture the best seal for the given application.

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

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 by design and depending on the performance requirement sensible seals, where
other parameters such as, handling, effective groove sizes and surface roughness are evenly important to achieve the desired results.

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

Except for the general recommendations found in this design manual, we cannot give specifi c warranties
for life-expectancy, leak-rate or other operational parameter.

Customers are always advised to qualify seals, preferably by real life test, or by similarity, in the exact configuration of their intended use.

Resilient metal seals from High Tech Metal Seals NV are used in the most extreme environmental conditions. Spring Energised Metal C Rings are used under extreme conditions where temperature can range from cryogenic up to extreme high temperatures, such as 800°C.
To serve the harsh conditions in today’s Oil and Gas exploration, High Tech Metal Seals NV designs and manufactures resilient metals seals which comply and exceed the ISO 15848 leakage requirements for valves intended for application with volatile air pollutants and hazardous fluids. High Tech Metals Seals are manufactured from high alloy materials so that the finished product complies with NACE MR0175 requirements. Silver plated Metal O rings or Metal C Rings, because of ductile layer are successfully used in high vacuum applications. Silver plated or PTFE coated spring energised C Rings and Metal C Rings comply and exceed the ISO 15848 leakage requirements, from cryogenic temperatures up to extreme high temperatures and pressures. In nuclear applications, particle research, and other radiation application, typically high load resilient metal seals, such as spring energized metal C Rings or Metal O Rings, with a ductile layer of silver are successfully used. High Tech Metal Seals NV, seals for extreme environmental conditions are particularly suited for high pressure. The system pressure assist in maintaining intimate contact with the mating flanges.
