Plastic gas/water pipes connecting pipe elbow

摘要

The device has a housing of two interlocking relatively turnable part housings (10,20), one with an intake socket (21), the other with an outlet socket (11). The outer housing (10) has a concave hollow part (15) as a front section (13) for the inner housing, and a convex spherical (25) end section (14) with flow channel (23). An electrical heater mat (50) causes a weldable plastic material in the contact faces between hollow and spherical parts to liquefy, and when it is switched off, the plastic solidifies and the set relative angles between intake and outlet sockets are fixed.
