Pool Brass Composite Unions - Female Thread
Swimming Pool Composite Unions ideal for connecting to all types of heat exchangers as the brass end is designed to allow for the expansion and contraction which comes from the temperatures generated by heat exchangers. Available in 1.5" & 2" sizes with either a male threaded or female threaded brass end.
Please be aware that swimming pool pipe work is sized from the INSIDE and subsequently LOOKS bigger from the outside (most people wrongly believe their pipe work is 2"). We have placed a picture under the PDF download section showing the 2 common sizes in relation to everyday standard AA & 9V Duracell batteries as an easily referable scale.
Please see our downloads section for exploded views of all the various fittings showing the different configurations for sockets, threads, male & female fittings.
ABS (Acrylonitrile butadiene styrene) is an extremely robust thermoplastic material which is ideal for swimming pool installations.
