17mm tubing is typically used as a lateral line on a bench,
table, or in a garden bed that will supply many individual plants. 17mm tubing
is generally the same size as ½” .700 OD poly tubing, and can use compression
fittings for that spec as well as 17mm barbed fittings. We do not recommend
using it with spin-loc fittings specified for .700 OD poly.
