Rain Bird TLF series Twist Lock Fittings

Rain Bird’s complete line of Twist Lock Fittings simplify the installation of all industry standard 1/2", 3/4" and 1" dripline and distribution tubing. They provide an even tighter seal on tubing by using high quality barbs and twist-locking nuts. Their unique barb design reduces insertion force while maintaining a secure fit.

Ideal for use with Rain Bird XFD, XFS and XFCV dripline, XF blank tubing, XT700, XBS and QF Header distribution tubing. Models include couplings, elbows, tees, caps and MPT threaded adapters.
