Description
150# Stainless Steel Cross ISO 49
150# Stainless Steel Cross Fittings are standard-pattern cast fittings designed to create intersecting branch connections in compatible threaded piping systems. The four-way configuration allows a main piping run to connect with two opposing branch lines, making the fitting useful where multiple flow paths must meet at a single connection point.
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.

Cross Fitting Design
A cross fitting provides four connection points arranged around a common fitting body. This allows two opposing branch lines to intersect a main piping run at 90-degree angles.
The configuration is useful where several piping runs must connect at a common point without using multiple separate tee fittings.
Four-Way Connection
The cross configuration can be used to distribute, combine, or redirect flow through multiple connected piping runs.
Because several flow paths meet within the same fitting, confirm system layout, flow requirements, nominal connection size, and operating conditions before installation.

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 fitting dimensions before ordering or installation.
Cross vs. Tee Fittings
Cross Fitting
- Four total connection points
- Creates two opposing branch connections
- Useful where multiple piping runs intersect
- Provides multiple flow paths within one fitting
Tee Fitting
- Three total connection points
- Creates one 90° branch connection
- Useful for a single branch from a main run
- Simpler configuration than a cross fitting
Common Applications
