Description
150# Stainless Steel Heavy Pattern Coupling ISO 49
150# Stainless Steel Heavy Pattern Couplings are standard-pattern cast fittings designed to join two compatible threaded pipe sections in a straight-line connection. The heavy-pattern body provides a robust coupling configuration while maintaining the corrosion resistance and installation advantages of stainless steel.
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 Coupling Design
A heavy pattern coupling is used to connect two compatible threaded pipe sections along the same centerline. The coupling provides female threaded connections from both ends within a single fitting body.
The heavy-pattern configuration provides a more substantial fitting body than lighter coupling styles while maintaining a compact straight-through connection.
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 coupling dimensions before ordering or installation.
