How Speedfit Works
Speedfit Fittings have a unique grip then seal construction made up of a collet with stainless steel teeth to grip the pipe and an "O" ring to provide a permanent leak proof seal.
Use of the Superseal Pipe Insert insures a double "O" ring seal.
An "O" ring at the head of the insert and the shape of the stem, provide a secondary seal against the bore of the fitting. A combination of this and the main "O" ring ensure a good connection.
The stem of the insert gives greater rigidity of the length of pipe within the fitting. A combination of this and the main "O" ring ensure a good connection.
The head of the insert has been designed for ease of insertion.
The additional benefit of Twist and Lock Fittings is that a twist of a screwcap locks the pipe in position and gives increased compression on the "O" ring for even greater security.

Handling Fittings and Pipe
Ensure fittings and pipe are kept clean at all times by keeping them in bags and boxes provided. Do not empty Speedfit products onto the floor area, and ensure all internal "O" Ring Seals are kept free from dirt and debris.
