A turn point for drip supply tubing

The Raindrip S5700UB Stretch n’ Lock Elbow gives compatible drip supply tubing a shaped corner fitting. It is listed for compatible 1/2 inch, 5/8 inch, or 0.710 inch tubing, which makes size checking the first step before it goes into a repair plan.

An elbow can help a supply line turn along a raised-bed edge, container row, greenhouse bench, or shrub route while keeping the direction change easy to see.

Useful for readable route corners

Route corners deserve attention because bends can move when soil, mulch, or foot traffic shifts nearby. A visible elbow gives that turn a named fitting and a clear spot to check during the first watering pass.

Store the fitting with the tubing size written on the pouch or bin. That small note keeps the repair shelf calm when several drip tubing sizes share the same cabinet.

Good match

This elbow fits gardeners maintaining compatible drip supply tubing around beds, rows, greenhouse benches, and container zones where a clean turn is part of the route.

It pairs well with end caps, compression couplings, pressure notes, filter notes, and route labels.

What to know

Confirm tubing size, press the fitting into place with steady pressure, and keep the corner uncovered during the first water run. Check for dampness at the connection before the line gets tucked back into the planting area.
