Brennan 10357 Straight Swivel Adapter Fnpsm X Mnptf

Product Description

The BRENNAN 10357 is a straight swivel adapter designed for industrial pipe connections requiring a rotating joint between fixed piping segments. It features a 1-11-1/2 Female National Pipe Straight Mechanical (FNPSM) inlet and a 1-11-1/2 Male National Pipe Taper Fuel (MNPTF) outlet. The swivel design allows rotational movement during assembly and service without twisting the connected hose or tubing. Constructed from steel, this adapter is rated to 3,000 psi and has an overall length of 2.37 inches. It is installed by pipefitters, hydraulic system technicians, and industrial maintenance trades in high-pressure fluid and pneumatic line applications.

This adapter is suited for industrial piping systems where alignment flexibility is needed at a fixed-thread connection point. The FNPSM x MNPTF configuration bridges a straight mechanical thread on the female side to a tapered fuel thread on the male side, making it useful in hydraulic circuits, compressed air manifolds, and fluid transfer systems operating at or below 3,000 psi. The 1-1/2 inch hex size accommodates standard open-end and adjustable wrenches for installation in tight quarters.

Key Features

• Straight swivel design allows rotational movement without twisting connected lines
• Rated to 3,000 psi for high-pressure industrial service
• FNPSM x MNPTF connection type bridges straight mechanical and tapered fuel thread standards
• 1-11-1/2 thread size on both male and female ends
• Steel construction for durability in industrial environments
• Compact 2.37-inch overall length suits space-constrained installations

Compatibility

Designed as an OEM-style replacement or service fitting for industrial piping systems using 1-11-1/2 FNPSM x MNPTF straight swivel adapter connections rated to 3,000 psi.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician. Depressurize and isolate the system completely before removing or installing any fittings. Use a properly sized open-end or adjustable wrench on the 1-1/2 inch hex to avoid rounding the fitting body. Apply thread sealant appropriate for the fluid type and pressure rating per the system manufacturer and applicable codes.
