Join or adapt an air line with the airline fittings here, including SIP bayonet fittings, Sealey Speedfit push-fit assortments and Draper BSP reducing unions. The Draper 25866 reducing union steps a 3/8" BSP parallel thread down to 1/4", and the 25867 steps 1/2" down to 1/4". Both Product Names give the two thread sizes and the BSP parallel thread form, so you can match them to your ports.
Choose by the connection you need to make: a bayonet half to suit a bayonet line, a Speedfit tube size, or a BSP thread size. In the assortment contents, Speedfit sizes are the tube's outside diameter in mm. Search by the part number in the Product Name, such as SIP 04080 or Sealey AB070JG. To match an unmarked fitting, send a photo of both ends on WhatsApp to 07754288583.
