A press coupling with stop joins two compatible sections of stainless steel pipe in a straight run. The internal stop provides a physical reference point for pipe insertion and helps position each pipe end within the fitting.

The fitting is installed using compatible stainless press tooling. Once properly positioned, the fitting is mechanically pressed onto the pipe to create the connection.

This configuration is useful for new installations, repairs, extensions, and other applications where a straight press-connected pipe joint is required.

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 pipe size, pipe material, temperature, conveyed media, seal compatibility, installation method, and the applicable Merit Stainless Press documentation.

• Confirm the required nominal fitting size before ordering.
• 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 the fitting and pipe outside diameters are compatible.
• Inspect the pipe end before installation.
• Prepare and insert the pipe according to Merit installation requirements.
• Insert the pipe fully to the internal stop.
• 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.
