Description
150# Stainless Steel Industry Pattern Half Coupling ISO 49
150# Stainless Steel Industry Pattern Half Couplings are standard-pattern cast fittings designed to provide a compact threaded connection point in stainless steel piping systems. The half-coupling configuration is useful where a full coupling is not required, making it well suited for branch connections, equipment connections, vessel connections, and general process piping applications.
The fitting family is available in AISI 304 or 316 stainless steel, conforms to ISO 49-1983 (E) dimensional requirements, and is listed as low lead certified to NSF/ANSI 61.

Industry Pattern Half Coupling Design
A half coupling provides a shorter fitting body than a full coupling and is designed for applications where only one threaded connection point is needed.
The compact profile makes it useful for branch connections, equipment connections, tank or vessel attachments, and other installations where minimizing fitting length is beneficial.
Half Coupling vs. Full Coupling
Half Coupling
- Shorter fitting body
- Designed for a single threaded connection point
- Useful for branch and equipment connections
- Compact installation profile
Full Coupling
- Longer fitting body
- Designed to join pipe from both ends
- Commonly used for straight in-line pipe connections
- Different application from a half coupling

- Commonly selected for more aggressive environments
- Useful in many chemical and process applications
- Often selected for marine or chloride-exposed service
Stainless Steel Construction
The stainless steel construction provides corrosion resistance while helping reduce contamination associated with rust, scale, and small particles that can occur with some other metallic piping materials.
The supplied product information states that the material resists corrosive attack from hundreds of industrial and chemical solutions and mixtures and provides greater strength at elevated temperatures.
NSF/ANSI 61 Low Lead Certification
This fitting is listed as low lead certified to NSF/ANSI 61, supporting use in compatible potable-water applications where applicable system and code requirements are met.
Always confirm the requirements for the complete piping system, local codes, operating conditions, and media compatibility before installation.
ISO 49 Standard Pattern
Dimensions conform to ISO 49-1983 (E), providing dimensional consistency for compatible standard-pattern cast stainless steel fittings.
