Male Half: Temperature Range -40°C to 120°C

Component Specifications

Definition

The male half is a precision-engineered component of a hydraulic quick coupler system designed to connect with the female half to establish a leak-proof, high-pressure fluid transfer pathway. It features external threads or locking mechanisms that engage with corresponding elements on the female half, ensuring secure mating under operational pressures up to 10,000 PSI. This component is critical for rapid connection/disconnection in hydraulic systems while maintaining system integrity.

Working Principle

The male half operates by aligning and inserting into the female half, where mechanical locking mechanisms (such as ball bearings, latches, or threaded connections) engage to create a sealed interface. When connected, internal seals (typically O-rings) compress against mating surfaces to prevent fluid leakage. Disconnection is achieved by manually or automatically releasing the locking mechanism, allowing safe separation without fluid spillage.

Materials

Carbon steel (AISI 1045/4140), stainless steel (AISI 304/316), or brass (C36000) with surface treatments like zinc plating, nickel plating, or black oxide coating for corrosion resistance. Hardness: 30-45 HRC for steel components.

Frequently Asked Questions

What is the difference between BSPP and NPT thread types on male halves?

BSPP (British Standard Pipe Parallel) threads create seals via O-rings or gaskets, while NPT (National Pipe Tapered) threads achieve sealing through thread engagement. BSPP is common in metric systems, NPT in imperial systems.

Can male halves from different brands be interchanged?

Interchangeability depends on thread standards, dimensions, and pressure ratings. While ISO-standardized parts may be compatible, always verify manufacturer specifications to prevent system failures.
