The Alfagomma Z-MHUN Two-Piece Fittings are straight, carbon steel hose end fittings designed for use with Male Hammer Union Fig. 1502, featuring an integral fitting with a lug nut. These fittings are specifically used with Alfabiotech 6000 and 10K cementing hoses, typically in high-pressure applications like those found in oil and gas operations. A ferrule is a small metal ring used to secure the hose to the fitting, ensuring a leak-free, durable connection. Two-piece fittings, such as these, are made up of two separate parts that interlock for easy maintenance or replacement, unlike one-piece fittings that are permanently assembled. The Z Series fittings are designed with a two-piece interlock insert, which requires both internal and external skiving to fit securely into the hose. The proper ZF1 Interlock ferrule is necessary for optimal performance, ensuring that the fitting provides a reliable, high-strength seal in demanding environments.
