Is the Brass Cap Under Nut, Type AI 13780 compatible with pipe OD ranges from 4 to 22 mm and compliant with EN 1254-2?

Yes. Brass Cap Under Nut, Type AI 13780 is compatible with pipe outside diameters from 4 to 22 mm and is manufactured in compliance with EN 1254-2.

Can the Brass Cap Under Nut, Type AI 13780 withstand high-temperature cycling and maintain a leak-free seal over long-term use?

Brass Cap Under Nut, Type AI 13780 is manufactured from high-quality brass and conforms to EN 1254-2, giving it strong baseline resistance to corrosion, mechanical stress and temperature fluctuations. These attributes make it well suited to applications that experience routine temperature changes and thermal cycling. Its precise design ensures a tight fit that minimizes leak risk and supports long-term sealing performance in typical residential and industrial piping systems for pipe diameters 4–22 mm. However, long-term leak-free performance under high-temperature cycling depends on the specific temperature range, cycling frequency, system pressure, type of fluid, and installation quality (torque, mating materials, use of suitable gaskets/seals). For moderate high temperatures within brass’s acceptable limits and correct installation, the Type AI 13780 should maintain a reliable, leak-free seal over time. For extreme temperatures, aggressive fluids, very rapid or frequent thermal cycling, or critical high-pressure service, consult the manufacturer for validated temperature/pressure ratings and consider testing or specifying components rated for those harsher conditions.
