Parker 701003 Barbed Hose Fitting 3/8 in Brass Connector

Product Description

The PARKER 701003 is a brass barbed hose fitting configured as a connector with a barb-to-female pipe end connection. It accepts 3/8-inch inside diameter hose on the barbed end and threads onto a 3/8-inch female NPSM port on the pipe end. The body is machined brass, suited for fluid transfer lines in HVAC, plumbing, and light industrial applications. The fitting is rated for service from -40 degrees F to 160 degrees F, making it appropriate for both chilled-water and low-temperature hot-water circuits. Licensed plumbers and HVAC mechanics are the typical installers for this type of fitting.

This connector is used where a flexible hose must terminate at a threaded female pipe port. Common install scenarios include equipment drain lines, condensate connections, water supply laterals, and low-pressure fluid transfer assemblies in residential and light commercial systems. The 3/8-inch barb size and female NPSM thread are standard dimensions found across a wide range of HVAC equipment and plumbing fixtures.

Key Features

• Barb-to-female pipe end connection joins flexible hose to threaded female NPSM ports
• Brass construction resists corrosion in water and light fluid service
• 3/8-inch barb accepts 3/8-inch ID hose directly without reducers
• Rated -40 degrees F to 160 degrees F for chilled and low-temperature hot-water lines
• Hex head size of 0.75 inches allows standard wrench installation
• Overall length of 1.5 inches keeps assembly compact in tight spaces

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 3/8-inch ID hose with a 3/8-inch female NPSM threaded port connection.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the fluid line before removing or installing any fitting. Apply thread sealant appropriate for the fluid service to the female NPSM threads before assembly. Tighten using a wrench on the hex head only — do not use the hose or barb shank as a grip point, as this can damage the fitting body.
