Parker BPHN4-4F Pneumatic Hose Coupling Nipple Brass

Product Description

The PARKER BPHN4-4F is a brass pneumatic hose coupling nipple designed for connecting air lines and pneumatic tool hoses in compressed-air systems. Threaded to the NPTF standard at 1/4-18, it provides a reliable, leak-resistant seal without the need for additional sealant tape in most applications. The 1/4-inch hose inside diameter makes it a common fit for light to medium-duty pneumatic circuits. Weighing just 0.056 pounds, this compact coupling is a field-replaceable component suited for maintenance technicians, industrial MRO, and shop-air setups. Brass construction resists corrosion and holds up well in typical compressed-air service environments.

This coupling nipple is used in pneumatic hose assemblies where a threaded male connection is required at a port, manifold, tool, or fitting body. Typical applications include shop air distribution lines, pneumatic tool connections, and light industrial automation plumbing. The NPTF thread form is common in North American pneumatic and fluid power systems, making this part a straightforward replacement or repair component across a wide range of compressed-air installations.

Key Features

• Brass construction provides corrosion resistance in standard compressed-air service
• NPTF 1/4-18 thread delivers a pressure-sealing fit at the thread form itself
• Nipple-style coupling for direct hose-to-port connections
• 1/4-inch hose inside diameter suits common light to medium-duty pneumatic hose sizes
• Compact and lightweight at 0.056 pounds for easy field handling and storage

Compatibility

Designed as an OEM-style replacement nipple coupling for pneumatic hose assemblies using 1/4-18 NPTF threaded ports in compressed-air systems.

Installation Notes

Installation of pneumatic hose couplings should be performed by a qualified technician familiar with compressed-air systems. Depressurize and bleed the air line completely before removing or installing any fitting. NPTF threads are designed to seal on the thread form, but inspect threads for damage before assembly and apply thread sealant per system requirements. Follow applicable OSHA and shop-air safety guidelines when working on pressurized pneumatic circuits.
