Is the Brass Jam Ring for Nut, Type AI 13740 compatible with external pipe diameters 4–22 mm and compliant with EN 1254-2?

Yes. The Brass Jam Ring for Nut, Type AI 13740 is compatible with external pipe diameters 4–22 mm and is fully compliant with EN 1254-2. It is made from high-quality brass for corrosion resistance and durability, provides a precise fit for leak-free connections, and is suitable for both new installations and replacements.

Can the Brass Jam Ring for Nut, Type AI 13740 withstand high-temperature environments without losing its sealing performance?

The Brass Jam Ring for Nut, Type AI 13740, made from high-quality brass and compliant with EN 1254-2, offers good durability and corrosion resistance that support reliable sealing in many demanding conditions. Brass retains mechanical strength and dimensional stability at moderate elevated temperatures typical for many plumbing and industrial applications, so the ring will maintain its sealing performance within those common service temperature ranges. However, brass has temperature limits: prolonged exposure to very high temperatures (well above typical plumbing service levels or brass annealing/softening ranges) can reduce its mechanical strength and may impair the ring’s grip and sealing effectiveness. For applications involving sustained extreme heat, thermal cycling, or temperatures approaching brass softening points, a specialized high-temperature material or additional sealing elements should be considered. In summary: the Brass Jam Ring for Nut, Type AI 13740 will withstand and maintain sealing performance in moderate high-temperature environments typical for plumbing and many industrial uses, but it is not intended for prolonged exposure to extreme temperatures where brass properties degrade.
