Enhanced performance compression solutionsFittings Introduction Pegler Yorkshire has upgraded the Kuterlite K900 range to Kuterlite K900-PRO As part of our continuous improvement and development programme we have studied the performance of compression fittings in the market and found certain applications where changes could further improve performance. With the intention of providing premium performance, Pegler Yorkshire has substantially increased the engineering safety factors in the Kuterlite K900-PRO product, principally the critical design characteristics of the compression nut. Kuterlite K900-PRO fittings are compatible with the following types of tube and pipe. n Copper tube to BS EN 1057 n Tectite PEX or other PEX pipe to BS 7291 part 3 Professional installation tips n PB pipe to BS 7291 Part 2 To ensure that these fittings enjoy a long serviceable life, n XPress Carbon steel system they must be correctly installed. tube or other carbon steel tube to EN 10305-2 sizes up Do not over-tighten nuts Do not contaminate to 28mm A matrix is provided at our website: Take care not to contaminate the threads www.pegleryorkshire.co.uk to help the or nuts with jointing compounds. n Tectite 316 system tube installer apply the correct amount of torque. or other stainless steel tubes This is expressed as partial or whole turns Use parallel threaded adaptors of the nut, and varies depending upon the This will help to avoid stressing the female to EN 10312 sizes up to 28mm type of pipe being used. threaded ends.
