This duotight stem to barb fitting is made from quality engineering grade polykeytone so it's strong, chemical resistant and will form a tight seal on our full range of duotight fittings.

This duotight barb to stem fitting is what you can use to connect a duotight fitting on one side then push tubing over the barb on the other side and secure with a hose clamp.  You can find the range of different hose clamps on our website here.
