Nipples

This category includes nickel-plated threaded inserts used in heating and plumbing systems. These fittings are designed for connecting pipes and components where a secure, leak-proof joint is required. They are commonly used in central heating, hot water distribution, and industrial piping systems operating at temperatures up to +120°C.

Available in standard metric thread sizes and Euroconic (EC) variants, these inserts are manufactured from CW617N nickel-plated brass for corrosion resistance and durability. Some models include EPDM O-rings for sealing, while others rely on the tight fit of the Euroconic taper.

How to choose

• Confirm the required thread type: metric (external-external) or Euroconic (EC) for tapered connections.
• Match the nominal size to the pipe or fitting being connected (e.g., 1/2", 3/4", 1", 5/4").
• Check if an O-ring is included (EPDM) or not, based on the sealing method required for the system.
• Verify compatibility with PN 10 pressure ratings and operating temperatures up to +120°C.

Frequently asked questions

Can these inserts be used with Euroconic (EC) fittings?
Yes, the RR 4700 N variant is specifically designed for Euroconic connections and does not require an O-ring.

What material is used for the inserts?
All inserts are made from CW617N nickel-plated brass, offering good resistance to corrosion and mechanical wear.
