Introduction of the new Mechanical Crimp Connection (MCC) that eliminates time-consuming, costly welding and ensures a reliable, leak-free connection was recently announced by Parker Hannifin Corporation. Welding processes, from pre-cleaning to non-destructive testing to post cleaning, reduce valuable equipment or project uptime and require additional labor costs. 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 adapter. Internal seals in the MCC adapter ensure a leak-free connection and protect against ingression. Compared to welding, MCC enables remarkably quick, easy mechanical crimping of adapters to piping.
MCC eliminates one of the key failure mode of welding: weld cracks. Weld cracks can form while the weld is hot, while it is cooling, or even due to fatigue or corrosion. MCC also eliminates the welding-induced contaminants that need to be flushed out after installation. Sizes and Configurations Parker MCC achieves NPS pipe connections in the most common weld sizes, ranging from 1" to 2". Whether the system is transferring fluid at lower pressures or operating at high dynamic hydraulic pressures, MCC offers a working pressure capability of nearly 5000 psi for many applications. MCC adapters are offered in carbon steel. Multiple end configurations, including retaining ring style code 61/62, male and female O-ring face seal, male and female 37° flare, and male and female NPT, are available to ensure system compliance with SAE and/or ISO standards.
MCC also offers full-range interchangeability with Parker Tube Fittings Division's extensive product lines, covering SAE and ISO specifications such as SAE J514, SAE J1453 and ISO 6162. Ideal for a wide range of applications in industrial processing, construction, large mobile equipment, oil and gas operations, and more, MCC gets equipment up and running sooner and projects completed faster.
