Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Orbit PVC-Lock 3/4 in. Push X 3/4 in. D MPT Plastic Pipe Adapter is a smart, time-saving solution for connecting a quick-connect push-to-fit line to a standard 3/4" male pipe thread. Built by Orbit in the PVC-Lock family, this adapter delivers a dependable transition without tools, leaks, or fiddling, making it ideal for irrigation, DIY plumbing projects, and garden setups.

What makes this adapter stand out

  • Fast, tool-free connection on one end with a reliable push-to-connect 3/4" fitting that grips tubing securely and detaches with ease for reconfigurations.
  • 3/4" male pipe thread on the opposite end (MPT) to thread into compatible fittings, valves, or threaded manifolds without special adapters.
  • Durable plastic construction designed for moisture-rich environments while remaining lightweight and corrosion-resistant.
  • Compact, space-saving profile fits tight spaces in irrigation lines, shelving, or compact plumbing installations where bulkier adapters won’t.
  • Versatile compatibility pairs seamlessly with PVC-Lock push-to-connect components and common 3/4" pipe-thread hardware for irrigation, hydroponics, greenhouse systems, and DIY projects.

Ideal use cases

  • Rapidly connect a push-to-connect watering line to a threaded spigot, manifold, or valve in irrigation setups and sprinkler runs.
  • Convert between push-to-connect tubing and standard 3/4" pipe threads in DIY plumbing or greenhouse irrigation systems.
  • Adapt temporary or modular irrigation layouts where quick assembly and relocation are beneficial, such as adjustable drip lines or portable garden setups.

Installation at a glance

  1. Prepare the 3/4" pipe thread end by cleaning threads and applying appropriate thread sealant or PTFE tape as needed for your connection.
  2. Thread the MPT end into the corresponding 3/4" threaded fitting or component until snug.
  3. Insert the 3/4" push-to-connect tubing into the other end until fully seated with a firm push.
  4. Check for leaks at both connections and run water to verify a secure, watertight seal.

Practical tips for best results

  • Confirm that both ends are compatible with your system’s tubing size and threading standards before installation.
  • When disassembling, support the push-to-connect end to prevent accidental withdrawal or tubing damage.
  • Keep the adapter clean and dry when not in use to preserve the integrity of the push-to-connect grip and threading surfaces.
