The go-to fitting option for most contractors will always be the standard 17mm barbed insert fitting. Another low cost alternative to a locking fitting, the 17mm fittings offered by Jain are made with regrind tubing plastic. This helps keep the cost low while reducing our carbon footprint. Available in elbow, tee and coupling configuration Jain will also be introducing a 3/4″ FPT Tee adapter in the coming months.
