Runs a 19mm poly irrigation line straight off a bigger 25mm tap.
The nut end screws onto the tap's 1 inch BSP thread and the barbed tail takes your 19mm poly pipe, which suits the larger taps you find on tanks, troughs and older properties. Holman recommend locking the pipe on with a 19mm ratchet clamp, which we stock right alongside it, and that stops the pipe creeping off the barb once the water's on.
Check your tap thread before you buy, because a standard 20mm garden tap needs the smaller 19mm x 20mm version instead. If you're not sure which one you've got, call us on (08) 8536 4333 or bring the old fitting into the shop at 34-52 Milnes Rd and we'll sort it.
