Parker Prestolok one-piece brass fittings are designed for fast assembly, disassembly and reassembly without tools, the company says. The fittings accept polyethylene, nylon or soft metal tubing. When the tubing is inserted in the fitting, radial claws on the elastic grab ring grip the tubing securely, and a nitrile O-ring forms a positive seal. The tubing can then rotate freely. The fittings have a working pressure range up to 300 psi from 0 to +200 degrees.
