Parker 127HB-6-4 Ball-end Joint Adapter Mnpsm X Mnpt

Product Description

The PARKER 127HB-6-4 is a ball-end joint adapter designed for industrial pipe and fluid system assemblies. It connects a 3/8-inch MNPSM (male national pipe straight mechanical) thread to a 1/4-inch MNPT (male national pipe tapered) thread, allowing angular articulation at the joint to accommodate misalignment without stressing connected fittings. Rated to 150 psi maximum working pressure and operable across a temperature range of -40 degrees F to 160 degrees F, this adapter suits demanding fluid transfer applications where rigid inline connections are not practical. Plumbers, pipefitters, and industrial maintenance technicians typically install this fitting in compressed air, hydraulic, and general fluid service lines.

This adapter is suited for use in industrial, commercial, and light mechanical service environments where a flexible joint connection is required between threaded pipe components. Its MNPSM-to-MNPT configuration makes it applicable in panel fittings, manifold assemblies, and equipment ports where thread conversion and angular movement are both needed. The compact size and low package weight of 0.05 pounds make it easy to carry as a service part on maintenance calls.

Key Features

• Ball-end joint design allows angular movement to reduce stress on connected fittings
• 3/8-inch MNPSM to 1/4-inch MNPT thread configuration for cross-standard thread conversion
• 150 psi maximum working pressure rating
• Operating temperature range: -40 degrees F to 160 degrees F
• Compact and lightweight at 0.05 pounds for easy field carry

Compatibility

Designed as an OEM-style replacement or service fitting for industrial pipe and fluid systems requiring an MNPSM x MNPT male-to-male ball-end joint adapter in 3/8 x 1/4-inch thread sizes.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified industrial maintenance technicians. Shut down system pressure and depressurize the line completely before removing or installing any fitting. Apply appropriate thread sealant or PTFE tape to tapered NPT threads per system requirements and applicable plumbing codes. Do not exceed the rated working pressure or temperature limits for this fitting.
