This range consists of End feed fittings wherein the soldering of pipe to fitting is done from outside using solder wire and flux.

Fitting material includes copper, gunmetal and DZR brass making them resistant to dezincification.
 
Sizes range from 15mm to 159mm.
 
 Jointing Methods
 
Step 1
The copper tube and fitting sizes should be compatible. Cut the tube end square without altering the tube’s shape hence making even contact with the tube stop in the body of the fitting.

All the burrs from inside and out of the tube should be removed.
 
Step 2
The socket of the fitting should be cleaned with a brush and the exterior of the tube with fine steel wool or a cleaning pad.
 
Step 3
Flux should be applied to the outside of the tube and inside of the socket.

In case of making the joint at one end only, one can insert a short uncleaned tube into the end(s) which is to be left unjointed using a wet cloth to keep it cool till the remaining joint(s) is made.
 
Step 4
The tube should be inserted fully into the fitting. The tube or fitting should be rotated and excess flux must be removed where possible.
 
Step 5
The tube and socket should be heated evenly using a Gas torch or Blow Lamp.
 
Step 6
Upon reaching the required temperature, the solder should be added. Due to capillary attraction the solder will be drawn into the joint. Successful jointing will show a ring of solder around the joint.
 
 
Step 7
Let the joint cool without moving it.

Clean the joint with a wet cloth and remove flux residues.
 
 
It has an integral ring of soft lead free solder contained within the fitting. When heat is applied to the fitting, the solder melts to provide a successful joint.

Fitting material includes copper, gunmetal and DZR brass making them resistant to dezincification.
 
Sizes range from 15mm to 67mm.
 
 Jointing Methods
 
Step 1
The copper tube and fitting sizes should be compatible. Cut the tube end square without altering the tube’s shape hence making even contact with the tube stop in the body of the fitting. Tube cutter can be used where practicable.

All the burrs from inside and out of the tube should be removed.
 
Step 2
The socket of the fitting should be cleaned with a brush and the exterior of the tube with fine steel wool or a cleaning pad.
 
Step 3
Flux should be applied to the outside of the tube and the socket.

In case of making the joint at one end only, one can insert a short uncleaned tube into the end(s) which is to be left unjointed using a wet cloth to keep it cool till the remaining joint(s) is made.
 
Step 4
The tube should be inserted fully into the fitting. The tube or fitting should be rotated and excess flux must be removed where possible.
 
Step 5
Apply heat with a low temperature torch,on evenly heating both tube and socket until a complete ring of solder appears at the mouth of the fitting. Do not apply excessive heat or additional solder.
 
Step 6
Let the joint cool without moving it.

Clean the joint with a wet cloth and remove flux residues.
 
 
This range includes flame free, demountable compression fittings.

The symmetrical compression ring provides a seal within the cone of the fitting and a two point seal on the tube.

The simple principle of the Conex compression joint is shown in the above diagram.

The compression ring is compressed between two differing tapers within capnut and fitting respectively. The sharper angle of the body taper constitutes a larger area of ring contact in the fitting body, thus preventing any tendency for the tube to revolve as the joint is being secured.

Tightening the capnut to secure the joint causes the compression ring to change form, making a perfect metal x metal seal that actually indents the tube on both points of contact.

Fitting material includes yellow brass and DZR brass making them resistant to dezincification.

Sizes range from 6mm to 159mm.
 
 
 Jointing Methods
 
Step 1
The copper tube and fitting sizes should be compatible. Cut the tube end square without altering the tube’s shape hence making even contact with the tube stop in the body of the fitting. Tube cutter can be used where practicable.

All the burrs from inside and out of the tube should be removed.
 
Step 2
Two alternative methods for making the joint are described below-
 
2[a]
The capnut and compression ring present in the Conex compression fitting are not removed while the tube is inserted into the fitting. One must check that the compression ring is in the correct position and that firm contact is established between the tube and the tube stop in the fitting.
   
  2[b]
The capnut and compression ring present in the Conex compression fitting are removed and placed on the tube. Then the tube is fully inserted into the fitting. One must check the sequence of placing the capnut and compression ring on the tube.
 
Step 3
The capnut is first tightened by hand then using a spanner required minimum number of turns are made.

For larger sizes apply a few drops of light oil to the screw thread before tightening the nut to help reduce the load required to reach the number of turns.

Jointing compounds and sealants are not required as Conex compression joint makes a metal x metal seal.
 
 
These are flame free push fit fittings, which enable fast fitting and require no tools, solders, and flux.

Fitting material includes copper and DZR brass making them resistant to dezincification.

Sizes available are 15mm, 22mm and 28mm.

 Jointing Methods
 
Step 1
The tube and fitting sizes should be compatible.
 
Step 2
Cut the tube end square with a tube cutter without altering the tube’s shape.
 
Step 3
All burrs must be removed and outside diameter of tube must be correctly chamfered to prevent damage to ‘O’ ring. A Deburring Tool must be used for this process.
 
Step 4
The required length of tube must be marked with a pen/pencil to ensure full insertion of the tube. This provides visual evidence that the tube has been fully inserted.
 
Step 5
Place the tube and fitting in a line. Once you locate the tube end within the mouth of the socket squarely touching the grip ring then push upto the tube stop. One can twist slightly for installation.
 
 
Step 6
Try and pull the tube away from the joint to check whether the joint is successful.
Conex >B< Press
Conex >B< Press fittings are user friendly and very quick to install, leading to savings on labour costs. It also offers the advantage of a flame free installation, therefore posing no fire risk. Conex >B< Press is a versatile press fitting system for use with hard, half-hard and soft copper tube, providing a secure, long-life, leak-proof joint. They are available in Copper and Red Brass and are suitable for use with copper tube to EN 1057.

To install >B< Press, a mechanical press tool with a compatible jaw with 'V' profile to fit each size of fitting is required. When pressure is exerted through the press tool the joint is permanently made and the fitting cannot be dismounted or re-used. The >B< Press system eliminates the need for solder, adhesives or additional jointing materials. The >B< profile has the advantage of a 3 Point Press, two mechanical presses either side of the bead and one hydraulic press crimping the o-ring.
 
Conex >B< Press Inox
Conex >B< Press fittings are also available in stainless steel (1.4401 annealed DVGW 541) and are compatible with stainless steel tube to EN 10312 (Series 1 & Series 2). These fittings also feature the pressing indicator (see page 266).

The fittings are suitable for drinking water without restrictions according to DIN 50930-6, water conduit for fire extinguishing (wet/dry), treated waters, rain water units. Other areas of applications include cooling water, WW heating installations, compressed air (oil free), solar installations and vacuum applications.

Sizes are available in 15-108.
