Parker PP-00394 Barbed Hose Male Connector 1/4 Mnptf Ss

Product Description

The PARKER PP-00394 is a barbed push-on hose male connector designed for secure, leak-resistant hose-to-thread connections in fluid handling systems. Constructed entirely from stainless steel, this fitting accepts a 1/4-inch inside diameter hose on the barbed end and threads into a female NPT port using a 1/4-18 MNPTF thread standard. The push-on barb design grips the hose ID mechanically, eliminating the need for clamps in low-pressure push-on hose assemblies. At 1.57 inches in overall length and weighing approximately 0.01 pounds, it is compact enough for tight-clearance installations. Licensed plumbers, industrial pipefitters, and fluid system technicians are the typical installers.

This connector is suited for residential and light commercial fluid handling applications where a threaded male NPT port must transition to a flexible barbed hose line. Common use cases include water treatment equipment, chemical feed systems, compressed air lines, and general-purpose hydraulic or pneumatic tubing assemblies that require a stainless steel fitting for corrosion resistance. The 1/4-18 MNPTF thread is a standard size widely used in instrumentation and plumbing manifolds. Sold in a package quantity of two, making it practical for multi-point installations or keeping a spare on hand.

Key Features

• Stainless steel construction provides corrosion resistance in wet, chemical, or outdoor environments
• 1/4-inch barb ID accepts standard 1/4-inch push-on hose without additional clamps
• 1/4-18 MNPTF threaded end for direct engagement with female NPT ports
• Compact at 1.57 inches overall length for tight-clearance panel or manifold installs
• Package quantity of two per order — practical for multi-point or backup stock

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4-inch push-on hose and 1/4-18 MNPTF threaded female ports in plumbing, HVAC, or industrial fluid handling applications.

Installation Notes

Depressurize and isolate the fluid line completely before removing or installing any fitting. Thread the MNPTF male end into the receiving female port by hand first to confirm thread engagement, then tighten with an appropriately sized wrench — avoid over-torquing stainless steel threads to prevent galling. Seat the hose fully over the barb until the hose end contacts the fitting shoulder for a secure mechanical grip. Follow applicable IPC or local plumbing code requirements for the specific fluid type and pressure rating of the assembly.
