Description
150# Stainless Steel Cap ISO 49
150# Stainless Steel Caps are standard-pattern cast fittings designed to close and terminate the end of a compatible threaded piping system. The compact threaded design provides a simple removable end closure while maintaining the corrosion resistance and durability of stainless steel construction.
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.

Cap Design
A threaded cap is used to close the end of a compatible male-threaded pipe or fitting. Unlike a permanent welded closure, the threaded design can be removed when future access to the piping system is required.
This makes the fitting useful for terminating pipe runs, isolating unused connections, or providing removable access points in compatible threaded piping systems.
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 cap dimensions before ordering or installation.
Cap vs. Plug
Cap
- Fits over a male-threaded pipe or fitting
- Uses an internal female-threaded connection
- Closes the end of a piping run
- Can be removed for future access
Plug
- Threads into a female-threaded opening
- Uses an external male-threaded connection
- Closes an internal port or fitting opening
- Different connection configuration from a cap
Common Applications
Commercial & General Piping
- End-of-line pipe closures
- Water piping systems
- Commercial plumbing
- General process piping
- Threaded stainless steel piping assemblies
Industrial & Corrosive Service
- Industrial process piping
- Chemical handling systems
- Corrosion-resistant piping applications
- Elevated-temperature service where compatible
- Applications where rust and scale contamination are undesirable

Frequently Asked Questions
What is a stainless steel cap used for?
A threaded cap is used to close the end of a compatible male-threaded pipe or fitting.
What pressure class is this cap?
This fitting is listed as a 150# stainless steel cap.
What stainless steel grades are used?
The supplied product information states that the fitting family conforms to AISI 304 or 316 stainless steel material requirements.
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.
How is a cap different from a plug?
A cap uses an internal female thread to fit over a male-threaded pipe or fitting, while a plug uses a male thread to close a female-threaded opening.
Can the cap be removed later?
Yes. Because it uses a threaded connection, the cap can be removed when access to the piping system is required.
Why use stainless steel for this fitting?
Stainless steel provides corrosion resistance and helps avoid contamination associated with rust and scale in compatible applications.
Where can I find fitting dimensions?
