This professional-grade NPT hose tail delivers leak-free, secure connections between 6.35mm internal diameter pneumatic hose and 1/4" NPT threaded equipment. Manufactured from high-quality brass with precision-machined threads and serrated barb profile, it's engineered for demanding workshop and industrial environments where reliability is non-negotiable.

Why This Fitting

When you're building or maintaining professional pneumatic systems, every connection point matters. This NPT hose tail represents the standard for trade-quality fittings—precision manufacturing, proven brass construction, and dimensional accuracy that ensures leak-free operation and extended service life in demanding applications.

The serrated barb design provides mechanical grip without damaging hose material, while the precision NPT thread profile guarantees reliable sealing when installed with appropriate thread sealant. Unlike economy fittings with inconsistent machining or inferior brass alloys, this connector delivers the performance professionals depend on day after day.

Technical Specifications

Common Applications

Installation Best Practices

• Verify hose has 6.35mm (1/4") internal diameter for proper fit
• Apply PTFE tape or liquid thread sealant to NPT threads—do not install dry
• Insert barb fully into hose end (warm hose slightly if needed for easier installation)
• Secure with hose clamp if required by application pressure or safety standards
• Thread fitting into NPT port hand-tight, then tighten 1-2 additional turns with wrench
• Avoid over-tightening which may damage threads or fitting body
• Pressure test system before commissioning

Compatibility & Requirements

Designed for pneumatic hose with 6.35mm (1/4") internal diameter. The 1/4" NPT male thread is compatible with standard pneumatic equipment including air compressors, regulators, filters, lubricators, and pneumatic tools featuring 1/4" NPT female ports.

Important: NPT threads are tapered and require PTFE tape or liquid thread sealant to achieve proper seal. The taper creates the seal—do not rely on thread engagement alone.
