Parker Hannifin has released a new fitting called the Mechanical Crimp Connection, or MCC, which is said to eliminate time-consuming and costly welding to join pipe. Because welding is eliminated, the MCC is also said to get rid of the inherent problems of weld cracks and welding-induced pipe contaminants.
The MCC consists of a one-piece crimp adapter with a specially designed bite ring and internal sealing. When crimped, the bite ring attaches to the pipe and secures the carbon-steel adapter. The internal seal blocks off ingression.
The MCC achieves pipe connection in the most common weld sizes, ranging from 1 to 2 in. It has a working pressure of 5,000 psi and comes in multiple end-configurations, including retaining ring style code 61/62, male and female O-ring face seal, male and female 37-deg flare, and male and female NPT. The mechanical connection also features interchangeability covering SAE and ISO specifications such as SAE J514, SAE J1453, and ISO 6162.
The MCC is produced by Parker’s Tube Fittings Division, which is part of the company’s Fluid Connectors Group, based in Cleveland. The group also makes rubber and thermoplastic hose and fittings, brass fittings and valves, and quick-connect couplings and assembly tools.
