Davant Whitespeed & GPF 15mm Metal Push Fit Pipe Insert

The Davant Whitespeed & GPF 15mm Metal Push Fit Pipe Insert is a high‑strength internal pipe support designed specifically for 15mm polybutylene (PB) barrier pipe used with push‑fit plumbing systems. It reinforces the pipe wall at connection points, ensuring a secure, leak‑free joint when installed with Davant Whitespeed and GPF push‑fit fittings.
