About Sealing materials

Sealing rings close the gap between a fitting and its mating part where the thread itself does not seal. The group holds 44 articles for threads from M5 to G 1, usually supplied in packs of 100.

What matters when choosing

• Material is the first decision. Vulcanised fibre and polyamide cover standard fittings, PA 6 and PVC are further plastic options, copper and aluminium seal metal to metal, and PTFE is intended for chemically loaded points.
• Temperature narrows the choice. Vulcanised fibre is rated to 105 °C, polyamide to 85 °C.
• The ring has to match the thread. Sizes are listed for threads from M5 to G 1, together with inside diameter, outside diameter and height H.
• Metal or plastic affects how much tightening force is needed and how far the ring deforms as the joint is pulled up.
• Besides rings, the group contains coil stock of 12 m length for sealing threads.

Typical applications

• Sealing fittings on service units and compressed air preparation.
• Gauge and measuring ports that have to stay tight and still be removable.
• Plugs on cylinders, valve blocks and housings.
• Hydraulic connections that call for a metal sealing ring.
• Thread sealing during retrofits and repairs in pipework.

Available materials are vulcanised fibre, polyamide, PA 6, PVC, PTFE, copper and aluminium. The 44 articles in this group come from Germany, Italy and the Czech Republic.
