Description
Stainless Press Male Adapter
Merit Stainless Press Male Adapters are designed to transition from compatible stainless steel press piping to a male threaded connection. The adapter combines a press connection on one end with a male pipe thread on the other, allowing stainless press systems to connect to compatible female-threaded valves, equipment, fittings, and other components.
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.

Male Adapter Design
A stainless press male adapter provides a press socket on one end and a male threaded connection on the other.
The press end connects to compatible Schedule 5 or Schedule 10 stainless steel pipe, while the male threaded end connects to a compatible female-threaded fitting, valve, manifold, or equipment port.
This configuration creates a direct transition between press piping and threaded components without requiring a separate coupling and threaded adapter.
Why Choose a Press Male Adapter?
Press-to-Thread Transition
- Connects stainless press piping to threaded components
- Male threaded end accepts compatible female threads
- Provides a direct transition in one fitting
- Useful for valves and equipment connections
- Can reduce the number of separate fittings required
Mechanical Press Installation
- Uses compatible press tooling on the pipe side
- No pipe threading required at the press connection
- No fitting weld required
- Supports repeatable mechanical connections
- Suitable for compatible stainless steel piping systems
