HOW SPEEDFIT WORKS

MAKING A GOOD CONNECTION

PREPARE THE PIPE

Fittings and pipe should be kept clean bagged and undamaged before use.

STANDARD SPEEDFIT FITTINGS

Push pipe up to stop

Pipe mark indicates

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 ensures 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.

	Barrier Pipe

Ensure the pipe is free of score marks. Cut the pipe square. When using Speedfit Barrier Pipe cut along an insertion mark. We recommend the use of JG Pipe Cutters.

Secondary Seal full insertion.

Standard Speedfit connections are made in the same way as Twist and Lock.

Push Pipe up to Pipe Stop. If the Speedfit Pipe has been cut correctly the insertion mark on the pipe will be level with the collet head.

The stem of the insert gives greater rigidity of the length of pipe within the fitting, reducing the chance of leaks if a side load is applied.

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.

To prevent damage to the ‘O’ ring remove all burrs and sharp edges. When connecting Speedfit Pipe use a Superseal Pipe Insert. A twisting motion will aid insertion. The insert should only be used with Speedfit Pipe.

TO DISCONNECT

Pull to check connection is secure and test the system. Our recommended test procedure is shown in our Technical Checklist on page 29.

NEW TWIST AND LOCK FITTINGS

Gap between Cap

and Flange

Pipe mark indicates full insertion

The fitting should be in the ‘unlocked’ position, this is shown with a small gap between the screwcap and the body flange.

Push the pipe fully into the fitting, up to the pipe stop. If the Speedfit Pipe has been cut correctly the insertion mark on the pipe will be level with the collet head. The ‘O’

ring on the Superseal Pipe Insert provides a secondary seal against the bore of the fitting. A good connection has been made.

If you are not using collet

clips, ensure that the

screwcaps are in the locked position.

Pull to check it is secure. It is good practice to test the system prior to leaving the site or before use. Our recommended test procedure is shown in our Technical Checklist.

ADDED BENEFIT TWIST AND LOCK

Twist the screwcap until it touches the body flange. This increases the ‘O’ ring seal around the pipe and locks the pipe into position.

Ensure that the system is depressurised.

The screwcap on Twist and Lock Fittings will need to be turned back to the unlocked position.

Push the collet square against the face of the fitting by using fingers or with the help of our collet release tool.

With the collet held in position the pipe can be removed.

The fitting can be used again without the need for replacement parts.

Do not insert fingers into the fitting as the stainless steel teeth may cause injury.

Remember to pressure test the completed installation according to the recommendations in our Technical Checklist.
