Legris 0163 21 13 Pipe Bushing Mbspt X Fbspp Brass

Product Description

The LEGRIS 0163 21 13 is a brass pipe bushing designed to reduce a 1/2 inch male BSPT thread down to a 1/4 inch female BSPP thread. It serves as a thread-reducing adapter in compressed air, hydraulic, and fluid distribution systems where BSPT male connections must mate with BSPP female ports. The bushing carries a maximum working pressure of 1,000 psi and a pressure rating of 3,626 psi, making it suitable for demanding industrial piping circuits. Plumbers, pipefitters, and industrial maintenance technicians install this fitting when transitioning between thread types or reducing line size within a manifold or valve block assembly.

This bushing is appropriate for both industrial and commercial piping applications where British Standard threads are specified. Common install scenarios include pneumatic distribution headers, hydraulic manifolds, and compressed air drop legs that require a step-down adapter between a larger male port and a smaller female port. The MBSPT x FBSPP configuration is standard in European-spec equipment and machinery imported to North American job sites. The fitting operates across a temperature range of -40 degrees F to 302 degrees F, supporting a wide variety of fluid and gas media.

Key Features

• Reduces 1/2 inch MBSPT to 1/4 inch FBSPP for thread-type and size transition in one fitting
• Brass construction provides corrosion resistance in air, water, and light hydraulic fluid service
• 1,000 psi maximum working pressure rated for industrial pneumatic and hydraulic circuits
• Wide temperature range from -40 degrees F to 302 degrees F covers most industrial environments
• Compact bushing profile installs directly into a female-ported valve, manifold, or block without additional adapters

Compatibility

Designed as an OEM-style replacement or service fitting for industrial piping systems requiring an MBSPT x FBSPP reducing bushing in brass construction.

Installation Notes

Installation is performed by licensed pipefitters or qualified industrial maintenance technicians. Depressurize and isolate the circuit completely before removing or installing any threaded fitting. Apply thread sealant or PTFE tape appropriate for the service media and pressure rating; do not over-tighten, as brass threads can be damaged by excessive torque. Verify that the mating port thread form matches BSPP before installation, as BSP and NPT threads are not interchangeable.
