Midland Industries 15021216 90 Deg Swivel Elbow Fnptf X Fnpsm

Product Description

The MIDLAND INDUSTRIES 15021216 is a 90-degree swivel elbow adapter designed for steel hydraulic pipe assemblies. It connects a 3/4-inch Female NPTF port to a 1-inch Female NPSM swivel port, allowing directional changes in a line while maintaining the ability to rotate the swivel end for alignment during installation. The NPTF thread on the fixed end creates a pressure-tight mechanical seal without relying solely on sealant. The NPSM swivel end provides rotational freedom to position downstream fittings cleanly. This fitting is appropriate for hydraulic plumbing work performed by pipefitters, hydraulic system technicians, and experienced plumbing trades.

The 15021216 belongs to the 1502 Series of steel pipe swivel adapters and is suited for hydraulic system plumbing where a 90-degree change of direction is required between a fixed female NPTF port and a swivel female NPSM connection. Typical applications include industrial hydraulic circuits, fluid power assemblies, and related steel pipe plumbing. The swivel design reduces stress on connected lines by allowing angular adjustment at the time of assembly.

Key Features

• 90-degree elbow configuration for direction changes in hydraulic pipe runs
• 3/4-14 Female NPTF fixed end provides a dry-seal pressure-tight thread connection
• 1-11-1/2 Female NPSM swivel end allows rotational positioning during installation
• Steel construction for durability in hydraulic service environments
• Part of the 1502 Series steel pipe swivel adapter family

Compatibility

Designed as an OEM-style steel pipe swivel adapter for hydraulic plumbing systems requiring a 90-degree transition from a 3/4-inch Female NPTF connection to a 1-inch Female NPSM swivel connection.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic system technician. Depressurize and isolate the hydraulic system completely before removing or installing any fittings. Apply thread sealant to the NPTF end as appropriate for the system fluid and pressure rating. Do not overtighten the NPSM swivel end; snug to hand-tight plus wrench-assist is typical practice, but follow the system manufacturer or applicable fluid power standards for final torque guidance.
