The Talbot Grippa is a universal fitting that connects MDPE onto a wide variety of existing lead, galvanised iron and copper pipes with no change of components. S imply push the pipe into the universal end of the fitting and tighten, no loose assembly of compo nents or special preparation of the pipe or cutting of threads. Ab, you managed to remove the two bolts on the inspection cover? Cool - that's the hard bit done. The cover will be held by paint, most likely, or a thin 'rust' bond, but nothing serious.

Our compression universal coupling fittings are available in sizes from 15-21mm x 20mm to 59-61mm x 63mm. Slide a pair of extractors (plastic or metal) in between the pipe and fitting and pull the pipe from the fitting

Now, tighten the nut with a wrench. Hold the body of the fitting with a second wrench to prevent it turning. This fitting will need to be done up very tight to ensure that the O ring seals against the lead pipe and that the gripper ring is moulded to the pipe shape fully. The friction ring prevents over tightening and crushing or misshaping the pipe out of shape. Do you think you are up to replacing all that lead pipe at some point? If so, I think you'll find it's fixed into that cast connector using mortar or similar, so that will need lots of gentle chipping away too, and try to avoid any of it falling inside that pipe. Select the appropriately sized fitting – each is designed for a specific range of diameters that it will securely connect to. Choose a straight section of the lead pipe and, with the water turned off and the pipework drained, cut the lead pipe ensuring that this is square and clean. If there are any markings on the lead at this point you will need to carefully file them off so that the size is not distorted. These couplings are designed to join MDPE pipe with MDPE, PVC, ABS copper, stainless steel, galvanised iron, or lead pipe. There may be situations where you need to make a connection to a lead pipe. You may have a leaking joint or fitting, or there may be an old lead pipe that needs to be capped off.

Replace grip ring by forming a figure 6 to reduce the diameter and insert it into the fitting the same way round as the old one was removed Now, assemble the joint. Place the compression nut over the pipe with its open side facing the end. Slide this along and follow it with the gripper ring then friction ring. Lastly, push the rubber O ring onto the lead pipe before mounting the coupling itself on the end of the pipe. Make sure that the lead pipe fully engages into the fitting body. Pull the rubber O ring and other components down to the fitting and hand tighten the compression nut.A common difficulty with this fitting is establishing the size of the lead pipe so that the correct connector can be bought. Lead is generally referred to by weight as well as diameter. So, you will find the following sizes:

Talbot Push fittings have an internal grip ring and O ring. As water pressure increases behind the rings the strength of the grip and seal increases in line with the pressure. TechTip: To determine the outside diameter of the pipe, wind a length of cotton twice around the pipe without stretching it and then measure its length. Customer Notice - Chemical Resistance: Polyacetal split rings and NBR o-rings, suitable for water, are supplied as standard. CPVC split rings and EPDM or FPM o-rings and seals are available. For aggressive chemical applications, the end user is advised to test suitability.

Connecting a Lead Lock Fitting

This PLASSON Plass4 universal coupler is designed to make a straight connection with metric MDPE and any metric PE/uPVC/copper/lead/galvanised steel pipe. Includes liner for MDPE.Able to withstand working pressures of up to 10bar, this WRAS approved product is suitable for use in systems conveying water and other fluids in urban and inter-urban infrastructure, industrial, mining, landscape and farming, as well as optical fibre duct systems. The TALBOT GRIPPA universal adaptor is an easy to use universal fitting that connects onto a wide variety of existing lead, galvanised iron and copper pipes withoout the need to change any components. The adapters are Remove the grip ring from the fitting and dispose (Important – note which way round the grip ring is inserted) Philmac says that their Universal Transition Coupling can be used on a live pipe but wherever possible it is easier (and drier) to switch off the water and drain down first. Examples of Use of Lead to Copper Fittings So, as said above, use a sharp cold chisel or even a wood chisel you don't mind messing with, or anything like that such as a flat-bladed screwdriver, and work all around the cover's joint with the pipe. Use LOTS of gentle taps with a hammer rather than a few massive wallops - ok, it ain't going to break, but, well, chust to be sure it don't...
