Before you order
One O-ring sits in the outer groove of the pipe, the other in the inner groove of the fitting. When the pipe is pushed in, both rings engage the opposite grooves, sealing and locking the joint. The joint stays slightly flexible for adjustment, and without glue there are no stress cracks. LILIE recommends silicone lubricant for easier assembly.
