Description
150# 304 Stainless Steel Heavy Pattern Half Coupling ISO 49
150# 304 Stainless Steel Heavy Pattern Half Couplings are standard-pattern cast fittings designed to provide a compact single-end threaded connection in compatible stainless steel piping systems. The heavy-pattern body provides a robust connection point for branch, equipment, vessel, or other applications where a full-length coupling is not required.
The fitting family conforms to AISI 304 or 316 stainless steel material requirements and ISO 49-1983 (E) dimensional requirements. These fittings are also listed as low lead certified to NSF/ANSI 61.

Heavy Pattern Half Coupling Design
A half coupling provides a shorter coupling body intended for applications where only one threaded connection is required. It can be used as a compact connection point in branch piping, equipment, vessel, or other compatible piping assemblies.
The heavy-pattern configuration provides a more substantial fitting body while maintaining the shorter profile associated with a half coupling.
Half Coupling vs. Full Coupling
Half Coupling
- Shorter fitting body
- Designed for a single threaded connection
- Useful for branch or equipment connections
- Compact installation profile
Full Coupling
- Longer coupling body
- Designed to connect pipe from both ends
- Commonly used for straight in-line pipe connections
- Different configuration from a half coupling
Stainless Steel Construction
The stainless steel construction provides corrosion resistance while helping prevent 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 code and system requirements are met.
Always confirm complete system requirements, 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.
Use the manufacturer dimensional document below to confirm half coupling dimensions before ordering or installation.

Frequently Asked Questions
What is a heavy pattern half coupling used for?
A heavy pattern half coupling provides a compact single-end threaded connection and can be used for branch, equipment, vessel, or other compatible piping connections.
What pressure class is this half coupling?
This fitting is listed as a 150# stainless steel half coupling.
What material is this listing for?
This listing is for 304 stainless steel. The supplied product information states that the fitting family conforms to AISI 304 or 316 material requirements.
What makes this a heavy pattern fitting?
The heavy-pattern configuration uses a more substantial fitting body while retaining the shorter profile and single-connection function of a half coupling.
How is a half coupling different from a full coupling?
A half coupling has a shorter body and is designed for a single connection, while a full coupling is typically used to join two pipe sections from opposite ends.
What dimensional standard applies?
The fitting dimensions conform to ISO 49-1983 (E).
Is this fitting low lead certified?
Yes. The supplied product information lists the fitting as low lead certified to NSF/ANSI 61.
Why use stainless steel for this fitting?
Stainless steel provides corrosion resistance and helps avoid contamination associated with rust and scale in compatible applications.
Can this fitting be used in corrosive environments?
The supplied product information states that the stainless steel material resists corrosive attack from hundreds of industrial and chemical solutions and mixtures. Actual compatibility should be confirmed for the specific media and operating conditions.
