Description

Securely Transition from Rigid Pipe to Flexible Tubing.

The PVC Insert x Barb Adapter is the professional's choice for connecting flexible polyethylene tubing directly to a rigid PVC manifold or lateral line. Designed with a specialized "Spigot" end, this fitting is engineered to solvent weld inside the socket of a standard PVC fitting (such as a Tee, Elbow, or Coupling), providing a flush, low-profile connection that must be secured with Hose Clamps.

Whether you are stepping down from a main water supply to a drip irrigation zone or creating a custom manifold layout, this Schedule 40 PVC adapter ensures a leak-free transition. The sharp, multi-ribbed barbs grip the interior of the tubing tightly, while the spigot end eliminates the need for extra pipe nipples, saving you space and installation time.

Why Choose PVC Spigot Adapters?
  • Space-Saving Design: The spigot end fits completely inside an existing PVC hub, reducing the overall length of your assembly compared to threaded adapters.
  • Permanent Bond: Creates a solvent-welded joint on the PVC side that is as strong as the pipe itself, preventing leaks or loosening over time.
  • High-Flow Transition: The smooth internal bore minimizes turbulence and pressure loss as water moves from rigid pipe to flexible tubing.
  • Durable Construction: Molded from virgin Schedule 40 PVC, offering excellent resistance to corrosion, UV rays, and chemical fertilizers.
  • Versatile Sizing: Available in a wide range of sizes and reducing combinations to match any system requirement.

How to Install: A Step-by-Step Guide

This installation requires two different connection methods.

Step 1: Solvent Weld (PVC Side)
Clean the PVC fitting socket (e.g., Tee or Elbow) and the Spigot end of the adapter. Apply PVC Primer to both surfaces, followed by PVC Glue. Insert the spigot fully into the socket and twist a quarter turn to set. Allow to cure.

Step 2: Prepare Tubing
Slide a stainless steel hose clamp over the end of your poly tubing. If the tubing is cold or stiff, dip the end in warm water to soften it.

Step 3: Insert Barb
Push the poly tubing over the barbed end of the adapter. Ensure the tubing covers all the barb ridges and sits flush against the body of the fitting.

Step 4: Secure Clamp
Slide the clamp into position over the barbs (but not at the very edge) and tighten securely with a nut driver or screwdriver. This prevents blowouts under pressure.

✔ Compatibility Check

Ensure you have the right parts:

  • Spigot End: Fits INSIDE a standard PVC fitting socket (Tee, Elbow, Coupling). It does NOT fit over PVC pipe.
  • Barb End: Fits INSIDE Polyethylene Tubing (Standard or Oval Hose).
  • Fastening: Requires PVC Glue for the spigot side and Hose Clamps for the barb side.
  • It is NOT threaded.

Complete Your System

Get everything you need for a permanent, leak-free installation:

  • Hose Clamps: Mandatory for securing the poly tubing to the barb.
  • PVC Glue: The solvent cement required to bond the spigot end.
  • PVC Primer: Prepares the PVC surfaces for a strong weld.
  • Poly Tubing: The flexible supply line that connects to this adapter.
