Parker 30 Series has a locking mechanism that consists of pawls (or pins) which act directly on the sleeve, thereby causing the sleeve to automatically retract when the mating nipple is inserted.

30 Series couplings are push type Single Shut-Off couplings and mate with industrial interchange design nipples. .

Common applications: compressed air, water, grease, paint, limited vacuum and limited gases.
