The PVC Male Slip Insert x MPT (also known as a "Fitting Adapter" or "Street Adapter") allows you to add a Male Pipe Thread (MPT) outlet directly into an existing PVC fitting. Before you start cutting pipe, make sure you have a reliable pair of cutters to ensure clean, square cuts for a leak-free bond. We offer several sizes to fit your specific pipe needs, including 1", 1-1/2", and 2" models, as well as the robust Fiskars PVC Cutter.
Unlike a standard male adapter that fits over pipe, this unique fitting features a Spigot end designed to glue inside the slip socket of a Tee, Elbow, or Coupling. This compact design is perfect for tight spaces where you need to transition to threaded components—like ball valves, filters, or risers—without adding extra pipe length. As one of our most practical irrigation fittings, it ensures a robust, corrosion-resistant connection for professional and residential systems alike.
Verify your connection types before purchasing.

Step 1: Prep the Slip Joint
Clean the Spigot end of this adapter and the Slip Socket of your target fitting (e.g., Tee or Elbow). Apply Purple Primer to both surfaces.
Step 2: Glue
Apply PVC Glue to the primed areas. Immediately insert the Spigot end into the fitting socket, twisting a quarter turn. Hold for 30 seconds to set.
Step 3: Prep the Threads
Wrap the Male Pipe Threads (MPT) with 3-5 layers of thread seal tape in a clockwise direction.
Step 4: Connect Accessory
Screw your Female Pipe Thread (FPT) valve, filter, or riser onto the adapter. Hand-tighten firmly, then use pliers for a final half-turn if necessary.
