4 00 Page 1 Service Connections -Self Tapping Ferrule StrapsService Connections for Rigid and PE Pipes2 EBCO Bronze Self Tapping Ferrule StrapsEBCO Bronze Self Tapping Ferrule Straps for PE, PVC and AC mains pipe incorporatean integral ferrule with a self contained cutter, eliminating the need for drillingmachines. Straps are made from aluminium bronze or gunmetal or a combination ofaluminium bronze or gunmetal and plastic making the product durable and corrosionresistant. The strap also uses a specially designed cutter, which tests show greatlyreduces the risk of bursting a PVC main or creating a swarf blockage whilst bronze Straps have the added benefit of reduced Straps and Ferrules No special equipment or controlled conditions neededThe fitting has an integral cutter and requires only a spanner and standard ferrule key toinstall and carry out the drilling operation, dry or underpressure and in wet and congestedtrench conditions making it a viable alternative to electrofusion Integral cutterThe integral cutter is designed to greatly reduce the risk of fracturing PVC pipe during thedrilling procedure.

5 Its design also reduces the chance of swarf blockage whilst tapping byretaining the polyethylene/PVC slug. The cutter also provides a shut off facility once thetapping has been made Range of OutletsThe EBCO Self Tapping Ferrule strap can be supplied with a variety of banjo outlet types tosuit Copper, Male Threaded and PE pipe (both Barrier pipe for use in contaminated landsites and conventional PE range of EBCO Self Tapping FerruleStraps can supply outlet types to suit a widerange of Service pipe material and in a rangeof sizes.

6 (To meet the requirements of the WRAS (WaterRegulations Advisory Scheme) it is necessary touse an insert or liner with metric MDPE servicepipe to BS 6572:1985, BS 6730 and HPPE toWIS 4-32-13 for below ground use in the UK. Theliner is not an integral part of the EBCO Push Fitconnection and for polyethylene pipe other thanthe PE pipe material shown above use of the lineris optional. If a liner is not used the connection willstill substantially exceed most international performance requirements.) Once the liner is inserted into the pipepush the pipe fully into the PE end, pasttwo points of resistance, until it is Threaded Outlet Ensure the metal pipe is male threadedto the correct BSP size and apply sufficient PTFE tape to the male threadto aid the sealing process.

Testand tighten further if OutletEnsure the pipe is cut square then disassemble the end of the fitting to be connected,slide the thrust nut (1) then the friction washer (2), then the compression gland (3)over the end of the pipe to be connected. Insert the serrated insert (4) into the pipeand securely hammer it fully home with a soft faced mallet. Place the end of the pipeinto the banjo s body (5) and screw the thrust nut fully into the body, securely locatingthe friction washer and sealing rubber inside the body of the fitting. Once the thrustnut has been hand tightened use a spanner and tighten a further 11/2to 2 turns toform a fully sealed connection .

9 For easy, trouble free installa-tion the steps detailed below should be selecting the correctly sized strap forthe main, check that the cutter is retractedup into the stem and does not protrudethrough the bottom of the Fit the top half of the strap on the mainensuring that the sealing ring is correctlypositioned between the main and theunderside of the strap boss (see Fig. 1). Locate the bottom half of the strap belowthe top half and, using the two nuts andbolts provided, bolt the two halves togeth-er and tighten evenly. Make sure that thestrap sits squarely on the main and thentighten each nut a further two and a halfturns, a torque setting of approximately10 lb/ft ( Nm)The tapping procedure for the SelfTapping Ferrule strap is as follows:3.

10 Remove the plastic top plug and using theferrule key, screw down the self tapping cutter/plug until it bottoms on the seat(see Fig. 2). Do not over-tighten, a torqueof no more than 10 Nm, lb/ft is Wind the cutter/plug back to allow asmall amount of water to go to waste toflush out any debris (see ).5. Wind the cutter/plug back down onto itsseat to seal off the connection (do notovertighten).6. Connect the Service pipe to the banjo .7. Ensure the top cap is tightened down onto the banjo (hand tight plus a 1/2turn,15 Nm - 11 lb/ft) then wind thecutter/plug back to seal in the top cap (donot overtighten, a torque of no more than6 Nm, lb/ft is needed).
