Mj5 Clamping Nut 42051 Good Quality WaterJet Pump Parts Supplier

The MJ5 Clamping Nut 42051 is a precision-engineered high-pressure fitting component designed to securely fasten and seal MJ5-style tubing and connectors in WaterJet Cutting Machines and intensifier pump systems. It provides a strong, vibration-resistant mechanical lock that maintains a leak-free joint under continuous ultra-high-pressure operation, ensuring reliable and efficient fluid transfer between the pump, manifolds, and cutting head.

Manufactured from hardened stainless steel or nickel-chrome alloy, the 42051 MJ5 clamping nut offers exceptional tensile strength, corrosion resistance, and pressure stability. Each nut is CNC-machined to precise thread tolerances, guaranteeing perfect engagement with MJ5 fittings and adapters such as the MJ5 to IWP Adapter 42012. The internal sealing geometry is engineered for optimal contact pressure, preventing leaks and maintaining stable system pressure up to 60,000 psi (4000 bar).

The MJ5 Clamping Nut 42051 is fully compatible with major waterjet system brands, including KUNDA, KMT, FLOW, and OMAX, and fits a wide range of OEM and aftermarket high-pressure assemblies. It is used in pump outlets, manifold assemblies, cutting head inlets, and high-pressure tubing joints where secure, precise, and durable connections are essential.

Ideal for metal fabrication, stone cutting, ceramic processing, and composite machining, this clamping nut ensures safe high-pressure sealing, long service life, and easy maintenance, supporting consistent, high-efficiency waterjet operation.
