Description

Stainless Press Reducer Bushing

Merit Stainless Press Reducer Bushings are designed to reduce from a larger compatible stainless press connection to a smaller press connection within the same piping system. The compact bushing configuration provides an in-line size transition without requiring a separate reducer assembly.

Merit Stainless Steel Press Fittings are designed for use with Schedule 5 or Schedule 10 Type 304/304L or 316/316L stainless steel pipe conforming to ASTM A-312. The stated working pressure range is from full vacuum to 300 PSI (20.7 bar) on Schedule 5 and Schedule 10 stainless steel pipe.

Reducer Bushing Design

A press reducer bushing provides a compact transition between different nominal sizes within a compatible stainless steel press piping system.

The reducing configuration allows a smaller pipe size to be incorporated into a larger press connection without requiring a longer multi-fitting reduction assembly.

This type of fitting is useful where space is limited or where a direct press-to-press size transition is preferred.

Why Choose a Press Reducer Bushing?

Compact Size Transition

Reduces between different nominal press sizes
Provides an in-line transition
Can reduce the number of separate fittings required
Useful in compact piping layouts
Maintains a press-connected system

Mechanical Press Installation

Uses compatible press tooling
No threaded joint required
No fitting weld required
Supports repeatable mechanical connections
Suitable for compatible stainless steel piping systems

Reducer Bushing vs. Reducing Coupling

Reducer Bushing

Compact reducing configuration
Designed to transition directly between different press sizes
Useful where overall fitting length must be minimized
Maintains a straight piping run
This product configuration

Reducing Coupling

Provides a straight in-line size transition
Typically has a coupling-style body
Connects different nominal pipe sizes
May have greater overall length depending on design
Different fitting configuration from a reducer bushing

Compatible Stainless Steel Pipe

304 / 304L Stainless Steel

Compatible pipe material identified by Merit
Schedule 5 or Schedule 10 pipe
Pipe must conform to ASTM A-312
Verify pipe outside diameter and condition before installation
Confirm chemical compatibility for the intended media

316 / 316L Stainless Steel

Compatible pipe material identified by Merit
Schedule 5 or Schedule 10 pipe
Pipe must conform to ASTM A-312
Suitable where the specified system requires 316/316L pipe
Confirm chemical compatibility for the intended media

Pressure Range

Merit states that its Stainless Steel Press Fittings have a working pressure range from full vacuum to 300 PSI (20.7 bar) when installed on compatible Schedule 5 or Schedule 10 stainless steel pipe.

System suitability should be confirmed based on fitting size, pipe material, temperature, conveyed media, seal compatibility, installation method, and the applicable Merit Stainless Press documentation.

Installation & Selection Guidance

Confirm both the larger and smaller nominal sizes before ordering.
Verify the reducer bushing orientation for the intended piping layout.
Use only compatible Schedule 5 or Schedule 10 stainless steel pipe.
Confirm pipe is Type 304/304L or 316/316L stainless steel as required.
Verify that the pipe conforms to ASTM A-312.
Confirm all press connections are compatible with the selected pipe sizes.
Inspect and properly prepare pipe ends before installation.
Insert components to the required depth before pressing.
Use compatible press tooling and jaws approved for the Merit Stainless Press system.
Follow the applicable pressing sequence and tooling instructions.
Confirm system media compatibility using the Merit chemical compatibility chart.
Verify that the full-vacuum-to-300-PSI working range is suitable for the intended system.
Review applicable approvals and submittal requirements before specifying the fitting.
Installation should follow Merit instructions and applicable piping codes and project requirements.

Frequently Asked Questions

What is a stainless press reducer bushing used for?

It is used to transition between different nominal sizes within a compatible stainless steel press piping system.

Does this fitting change pipe direction?

No. A reducer bushing provides an in-line size transition rather than changing the direction of the piping run.

How is a reducer bushing different from a reducing coupling?

Both provide a size transition, but a reducer bushing uses a more compact bushing-style configuration while a reducing coupling uses a coupling-style body.

What pipe is this fitting designed for?

Merit identifies the Stainless Press system for Schedule 5 or Schedule 10 Type 304/304L or 316/316L stainless steel pipe conforming to ASTM A-312.

What is the working pressure range?

The stated working pressure range is from full vacuum to 300 PSI (20.7 bar) on compatible Schedule 5 and Schedule 10 stainless steel pipe.

Does this fitting require welding?

No fitting weld is required. The connection is completed using compatible press tooling.

Can this fitting be used with both 304 and 316 stainless steel pipe?

The supplied Merit information identifies Type 304/304L and 316/316L stainless steel pipe as compatible when the pipe also meets the specified schedule and ASTM A-312 requirements.

What pipe schedules are compatible?

The supplied information identifies Schedule 5 and Schedule 10 stainless steel pipe.

Where can I verify the exact reducer sizes?

Use the Merit Stainless Press Dimensional Catalog in the Product Documents section above.

Where can I check chemical compatibility?
