The 1/2" Compression x Spigot Adapter is the professional choice for converting hard-piped sprinkler lines into flexible drip zones. This compression adapter glues into any 1/2" PVC slip fitting and allows 1/2" poly tubing to be inserted into the other end. It provides a permanent, low-profile connection that is ideal for extending drip lines from existing PVC manifolds, tees, or elbows.
Unlike threaded adapters that require tape and tightening, this fitting is solvent-welded directly into a PVC socket for a bond that is as strong as the pipe itself. On the downstream side, the reliable compression ring grips your 1/2" polyethylene tubing securely, creating a leak-proof seal without the need for clamps.

Requires PVC Primer and Glue (Solvent Cement).
Step 1: Prep the Surfaces
Clean the outside of the adapter's spigot end and the inside of the 1/2" PVC fitting hub. Apply Purple Primer to both surfaces.
Step 2: Glue the Spigot
Apply PVC Glue to the spigot and the fitting hub. Insert the adapter fully, twist a quarter turn to distribute the glue, and hold for 30 seconds to bond.
Step 3: Insert Tubing
Once the glue is set, cut your 1/2" poly tubing squarely. Push it into the compression end of the adapter. Rock the tubing back and forth while pushing firmly until it passes the internal resistance ring (approx. 1/2" to 3/4" deep).
