Description
150# Stainless Steel Locknut ISO 49
150# Stainless Steel Locknuts are standard-pattern cast fittings designed to secure compatible threaded components in place within stainless steel piping and mechanical assemblies. Their compact threaded design provides a practical means of locking fittings, nipples, or other threaded components against a mating surface.
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.

Locknut Design
A locknut is used on a compatible threaded component to help hold that component in position against another fitting, panel, surface, or assembly.
Its compact profile makes it useful where a secure threaded retention point is needed without adding significant overall fitting length.
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 locknut dimensions before ordering or installation.
