Midland Industries 5404208 Reducing Hex Pipe Nipple

Product Description

The MIDLAND INDUSTRIES 5404208 is a reducing hex pipe nipple designed to connect two male NPTF threaded ports of different sizes in hydraulic and fluid-transfer systems. It steps down from a 1-1/4 inch male NPTF connection on one end to a 1/2 inch male NPTF connection on the other. The body is constructed from steel, providing the strength and pressure resistance required in demanding hydraulic applications. Thread specifications are 1-1/4-11-1/2 on the larger end and 1/2-14 on the smaller end, conforming to NPTF standards for dryseal performance. The hex body allows standard wrench engagement for secure, leak-resistant installation.

This nipple is suited for use in hydraulic plumbing circuits, industrial fluid lines, and mechanical systems where a reduction between two male-threaded ports is required. Typical installations include manifold assemblies, pump ports, valve bodies, and inline adapter configurations. It is commonly installed by hydraulic technicians, industrial maintenance mechanics, and plumbers working on high-pressure fluid systems in both commercial and industrial settings.

Key Features

• Reduces from 1-1/4 inch male NPTF to 1/2 inch male NPTF in a single fitting
• NPTF dryseal thread form on both ends for pressure-tight connections without sealant dependency
• Steel construction for high-pressure and high-load hydraulic service
• Hex body profile provides full wrench access during installation and removal
• Thread sizes: 1-1/4-11-1/2 and 1/2-14 per NPTF specification

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid-transfer systems using standard NPTF-threaded male port connections in the 1-1/4 inch and 1/2 inch size range.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with NPTF dryseal fittings. Depressurize and drain the hydraulic or fluid system completely before removing or installing any fittings. Apply thread sealant or PTFE tape only as required by system specifications, as NPTF threads are engineered for dryseal engagement. Tighten with an appropriately sized wrench to achieve full thread engagement without over-torquing the steel body.
