Parker 30182-4-6B Barbed Hose Male Connector Brass Nptf

Product Description

The PARKER 30182-4-6B is a barbed push-on hose male connector designed for secure, leak-resistant fluid transfer connections in hydraulic, pneumatic, and general industrial plumbing systems. Constructed from brass, this fitting features a 1/4-18 male NPTF threaded end and a 3/8 inch barb for push-on hose attachment. The NPTF thread form creates a pressure-tight mechanical seal without requiring additional sealant on compatible mating threads. At 1.78 inches in length, this compact connector suits tight-clearance installations. Licensed plumbers, HVAC technicians, and industrial maintenance professionals typically install this type of fitting in fluid or air distribution lines.

This connector is suited for residential and light commercial applications where push-on hose assemblies connect to NPTF-threaded ports. Common installation scenarios include HVAC condensate lines, compressed air distribution, refrigeration accessories, and general-purpose fluid handling where a reliable barbed-to-threaded transition is required. The brass construction offers good corrosion resistance across a range of media.

Key Features

• 1/4-18 male NPTF thread provides a pressure-tight mechanical seal
• 3/8 inch barb accommodates standard push-on hose assemblies
• Brass construction for corrosion resistance and durability
• Compact 1.78 inch length suits confined installation spaces
• Threaded connection type for straightforward hand-tightening and wrench finishing

Compatibility

Designed as an OEM-style replacement or service fitting for push-on hose assemblies requiring a 3/8 inch barb and a 1/4-18 male NPTF threaded port connection in hydraulic, pneumatic, or plumbing systems.

Installation Notes

Shut off fluid or air supply and relieve system pressure before removing or installing any threaded fitting. A licensed plumber or qualified technician should verify thread compatibility and confirm the mating port is female NPTF before installation. Use a properly sized wrench to tighten the fitting to hand-tight plus the appropriate turns per NPTF assembly practice — do not overtighten brass fittings. Ensure the push-on hose is fully seated past the barb bead and secured with a clamp where system pressure requires it.
