Series 21 Coded Quick Coupling

Brand: Rectus - by Parker

Parker's Coded Quick Coupling Series 21 is an industrial coupling system developed on the basis of series 21 with above-average flow rate for liquid and gaseous media.

This coupling system is developed for single-hand operation. The mechanical coding of the coupling and plug offers a guarantee for avoiding mix-ups between media when coupling, which is complemented by the color coding of the anodized sleeves.

A double shut-off version is available on request.
Features
  • No mix-ups between media due to the color and mechanical coding of coupling and plug
