The Davant Whitespeed & GPF 22mm Plastic Push Fit Pipe Insert is an essential internal pipe support designed for use with 22mm polybutylene (PB) barrier pipe in push‑fit plumbing systems. It reinforces the pipe at connection points, helping to create a secure, leak‑free joint when used with Davant Whitespeed and GPF push‑fit fittings.
