PLASS4 Universal Adapter Coupling - 15-22mm to 25mm

Product Information

These couplings are designed to join MDPE pipe with MDPE, PVC, ABS copper, stainless steel, galvanised iron, or lead pipe.

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.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.

Slide a pair of extractors (plastic or metal) in between the pipe and fitting and pull the pipe from the fitting 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 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 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.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 Tested to high standards - ISO 17885 for Water Applications, AS/NZS 4129, ISO 7/1, BS 21, DIN 2999, UNI 9561, NEN 3258, AS 1722, DIN 8076

Lead used to be used fairly extensively in plumbing but once the potential health risks associated with lead were understood, moves to change to alternatives were made. Nowadays lead is not allowed to be used for drinking water or, to use its formal description, potable water. However, old lead pipes still exist in many buildings. If you have an old lead pipe, the best solution is to remove it and replace it with copper. But, this is not always practical or possible. Universal couplings are pre-assembled and ready for use. Simply insert your chosen pipe into the fitting and tighten the nut. The UTC ends contain hard stainless steel gripping teeth which provide superior end load resistance. 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.

Lead Lock Compression Fitting

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.

Our compression universal coupling fittings are available in sizes from 15-21mm x 20mm to 59-61mm x 63mm. Push the pipe into the fitting with a slight twist ensuring the pipe can be felt passing through the grip ring and then the O ring. This will be felt as a slight resistance as it passes through each when inserting the pipe 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.

Examples of Use of Lead to Copper Fittings

Remove the grip ring from the fitting and dispose (Important – note which way round the grip ring is inserted) 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.
