COPPER FITTINGS FOR PLUMBING
Mfrd. by Yorkshire fittings
Integral Solder Ring Fittings for all your needs
BS 864 : Part 2 specifies hydraulic working pressures and temperatures for fittings assembled with tubes to BS2871. For 76.1mm and 108mm sizes of 'Yorkshire Potable' fittings , our own recommendations are given in the following table.
Smaller sizes of standard fitting can safely be used , at ambient temperatures, for much higher pressure than those indicated above . As part of the pipeline working room temperatures and under neutral or compressive stresses, fittings in sizes 6mm to 28mm can be used at pressures up to the maximum working pressures of tubes copper( Half hard or hard temper ) such as those to BS 2871, Table x or Table y.
Tin /copper lead free solder used in 'Yorkshire potable' fittings conforms to BS 864 : 99c with an approximate melting temperature of between 227degree C and 235degree C . The required jointing temperatures are readily achieved using a convenient heat source. See the following installation instructions for further details.
THE KUTERLITE 600 COMPRESSION FITTINGS RANGE
IMI Yorkshire Fittimgs Ltd also manufacture a range of precision made brass compression fittings that enable light gauge copper and steel tubes to be joined without the need for solder, blow torch or screw threading .
Kuterlite 600 fittings consist of a brass body with built-in stop for receiving the tube , compression rings which fit over the tubes and compression nuts. Little preparation of the tube is required prior to assembly and spanners are the only tools needed to make completely reliable joints. The action of tightening the nut compresses the specially shaped double grip Kuterlite ring onto the tube form a strong , secure, meta -to- metal joint.Kuterlite 600 fittings are ideal for use on above ground hot and cold water services and also are suitable for oil and low pressure gas lines. The fittings should be used with copper tube manufactured in accordance with BS2871 : part 1, tables w,x,y, (half hard) and z , DIN 1786 and other standard based on ISO 274.
Kuterlite fittings are accepted by and meet the requirements of the United Kingdom Water fittings by laws scheme
STANDARDS AND APPROVALS
(WRC) and UK muncipal authorities .They also comply with following standards :BS864:part2 (TypeA),Males BSP ends to BS 21,ISO 7,Female BSP ends to BS2779 ,ISO 228/ 1
Maximum permissible working pressures for Kuterlite 600 Fittings
when assembled with close tolerance, hard or half -hard copper tubes to BS2871: Part 1
DEZINCIFICATION RESISTANT ALLOY RANGE
Intented for hot and cold water services in certain areas where waters are known to support Dezincification of duplex brass fittings . The Kuterlite 900 Dezincification of duplex brass fittings. The Kuterlite 900 dezincification resisitant (DZR) range is designed for use with copper tubing to BS 864 : Part1 and installation and performance are identical to those of the Kuterlite 600 range.
