Male PE Elbow

Composition of fitting for multilayer - armoured pipe and dimensional characteristics

The Armoured Male PE Elbow fitting is made up of the following components:

• N. 1 Hot moulded CW617N brass body
• N. 1 Hot moulded CW617N brass ring-tightener ring nut
• N. 1 Brass tube-clamping ring CW614N derived from bar
• N. 2 O-rings in nontoxic NBR 70 rubber. Compound suitable for contact with potable water approved: ACS No. 09 CLP LI 008 – TZW KTW D1 D2 of 19 Dec 2007 – NSF ANSI 61 N° IG770-01
• N. 1 O-ring in nontoxic EPDM 70 rubber
• N. 1 PTFE washer

The male threading of our fittings is conical, not cylindrical, in compliance with standard UNI ISO 7 which defines the dimensions, the conical grade and the length of conical threading. The conical threading clearly provides a greater seal guarantee compared to a cylindrical one. In fact, the major water distribution companies normally request this. Furthermore, there are small cuts on the crest of the thread, knurling, in order to guarantee that Teflon or other types of materials suitable for sealing the thread will have better grip.
