CRIMP - ON Jointing & Troubleshooting Guide

                                              1 Tool Inspection:Make sure all tooling is in good operational condition and is approved for use on BUSH Crimp-On fittings. Ensure that when the tool is closed, the jaws are aligned and there is no gap between them. The jaws must be clean and free of any defects or debris. If a gap is visible between the jaws proceed to tool adjustment section and follow the instructions to ensure the tool is adjusted correctly. Warning: An incorrectly adjusted tool or damaged jaws may result in joint failure or tool damage. Tool Adjustment: The tooling will need to be adjusted if the jaws are not fully closed at the end of the crimping process or if the crimp gauge will not pass easily over both the indentations in the stainless steel sleeve after crimping. To adjust the tool follow the procedure below and then test the tool to ensure adjustment is correct. 1. L oosen LH and/or RH “Back Nuts” with Spanner. 2. T urn LH and/or RH “Adjustment Dials”, one increment at a time. 3. T ighten LH and/or RH “Back Nuts” with Spanner. 4. Crimp up joint and check with Crimp Gauge, until the Gauge passes easily over both the indentations in the stainless steel sleeve.
2、Cut the pipe to be joined using BUSH PE-X Pipe Cutters. Make sure the pipe is cut squarely, the end of the pipe to be joined has no rough edge and the internal and external surface of the pipe is undamaged (i.e there are no scores, cuts or scratches on the surface of the pipe).
3、Round the end of the pipe to be joined by inserting the BUSH Calibrating tool into the pipe, using the corresponding size. The Calibrating tool should be fully inserted into the pipe using a twisting action and repeated if necessary until it moves freely within the pipe.
4、Inspect the inside of the fitting to make sure they are free of dirt and grit etc.
5、Push the pipe slowly over the barbed fitting and within the stainless steel sleeve until the pipe is fully inserted and visible through the witness opening in the blue plastic stop ring. The pipe should be visible through ALL the witness openings.
6、Centralise the BUSH Crimping Tool so the jaws are aligned over the stainless steel sleeve. The jaws should be against the plastic stop ring and not over it. Slowly compress the tool until jaws are fully closed.
7To check the joint has been compressed correctly, use the crimp gauge supplied with the tool. If the gauge’s corresponding size easily passes over both the crimp indentations made in the stainless sleeve the joint is crimped correctly. If the crimp gauge will not pass easily over both the indentations in the stainless steel sleeve the crimping tool needs to be adjusted. Refer to the tool adjustment section. When the tool has been adjusted, re-crimp the joint and re-check with the crimp gauge. Repeat process until correct.

8、When soldering the connecting barbs (male or female) solder the brass connecting barbs first and allow to cool sufficiently before assembly. When assembling the fitting, ensure the plastic stop ring, both the O’rings and the stainless steel sleeve are installed correctly. (Refer to picture on the front page of this brochure for assembly detail)

9、Pressure test the complete installation in accordance with AS3500 parts 1, 4 and 5. Important: This system must be installed by a licensed plumber in accordance with this procedure otherwise warranty will be void.
