Description
ARGCO Grooved Weld-O-Let - Carbon Steel Cut Groove Branch Outlet
ARGCO Grooved Weld-O-Lets provide a welded branch connection with a cut-groove outlet for fire protection and other compatible low-pressure piping systems.
These Type 40 standard-weight branch outlets are manufactured from highly weldable black carbon steel and are designed to be welded directly to the run or header pipe. The grooved branch connection allows attachment to compatible grooved couplings, valves, fittings, and piping components while reducing the need for a conventional tee fitting.

Available Configurations
This listing covers multiple ARGCO Grooved Weld-O-Let configurations. Each variation combines a specific grooved branch outlet size with a compatible run or header pipe size.
Select the required SKU based on both dimensions. Two Weld-O-Lets with the same grooved outlet size may have different run contours for different header pipe sizes and should not be considered interchangeable.
Grooved Outlet
- Cut-groove branch connection
- Connects to compatible grooved piping components
- Outlet diameter varies by SKU
- Designed for approved grooved coupling systems
Welded Run Connection
- Contoured for installation on the run or header pipe
- Run size varies by SKU
- Weld-on installation creates permanent branch attachment
- Many models feature a chamfered profile
Carbon Steel Construction
ARGCO specifies a highly weldable grade of black carbon steel meeting or exceeding applicable ASTM material requirements for this fitting family.
The fittings are cleaned to bare metal internally and externally and protected with a rust inhibitor to help preserve the product during storage and handling prior to installation.
Because the fitting becomes part of the welded piping assembly, proper material compatibility, welding procedures, pipe preparation, and installer qualifications should be confirmed before installation.
Fire Protection Applications
Grooved Weld-O-Lets provide an efficient method of adding branch outlets to fire sprinkler mains and other compatible piping without installing a full-size reducing tee.
The fitting is welded directly to the header pipe, creating the branch opening and terminating in a grooved connection for attachment to downstream grooved components.
Typical uses can include sprinkler branch lines, riser assemblies, equipment connections, system modifications, and other approved branch connections in grooved fire protection piping.
Grooved Connection Benefits
Branch-Line Flexibility
- Connects directly to grooved-system components
- Eliminates a separate threaded outlet connection
- Supports common fire sprinkler piping layouts
- Available across multiple outlet and header sizes
Installation Efficiency
- Creates a branch without installing a conventional tee
- Welded attachment provides permanent header connection
- Grooved branch allows mechanical downstream assembly
- Useful for new installations and piping modifications
Pressure Rating & Approvals
ARGCO lists these Type 40 grooved Weld-O-Lets as UL, ULC, and FM products with a working pressure rating of up to 500 PSI CWP.
The stated pressure capability assumes use with listed or approved couplings, fittings, and related piping components having equal or higher pressure ratings.
The allowable working pressure of the complete piping assembly is determined by its lowest-rated component and by applicable system design, installation, and code requirements.
Quality & Manufacturing
ARGCO states that groove and bevel dimensions are checked for alignment, concentricity, depth, taper, and other applicable dimensional characteristics to conform to established industry standards.
Fittings are marked for product identification and include applicable size and approval information. The grooved Weld-O-Let family is manufactured in the United States.
Installation
Confirm the selected Weld-O-Let's branch outlet size and run/header size before installation. The fitting contour must match the intended pipe outside diameter.
Locate and prepare the branch opening according to the applicable system design and installation requirements. Position the Weld-O-Let squarely over the prepared opening and maintain proper alignment before welding.
Use qualified welding procedures and personnel appropriate for carbon steel fire protection piping. Avoid weld conditions that could distort the fitting, damage the groove, or restrict the branch opening.
After welding, inspect the completed connection and remove debris from the pipe interior. Verify that the cut groove remains clean and undamaged before installing the downstream grooved coupling or component.
All installation should comply with the applicable fire protection standards, approved system requirements, engineering specifications, and local codes.
Our team can help confirm your grooved outlet size, run or header pipe size, pressure requirements, and fitting configuration before you order.

What is an ARGCO Grooved Weld-O-Let?
It is a welded carbon steel branch outlet that attaches to a run or header pipe and provides a cut-groove connection for the branch line.
What material are these Weld-O-Lets made from?
ARGCO specifies highly weldable black carbon steel for this fitting family.
What does Type 40 mean?
ARGCO identifies this product family as Type 40 standard-weight cut groove welded outlets.
Are the Weld-O-Lets UL listed?
ARGCO identifies the grooved Weld-O-Let family as UL and ULC listed.
Are they FM approved?
Yes. ARGCO identifies the family as FM approved.
What is the maximum working pressure?
ARGCO lists a working pressure of up to 500 PSI CWP when the outlet is used with listed or approved couplings and fittings having equal or higher pressure ratings.
Are these made in the USA?
Yes. ARGCO identifies this grooved Weld-O-Let family as made in the USA.
How do I select the correct variation?
Match both the grooved branch outlet size and the run/header pipe size. The header contour varies by run size, so selecting only by the branch size is not sufficient.
What does "run" mean in the variation description?
The run is the main or header pipe onto which the Weld-O-Let is welded. For example, a 2" grooved x 6" run fitting provides a 2" grooved branch outlet on a fitting contoured for a 6" run pipe.
What does "with chamfer" mean?
The chamfer refers to the prepared profile of the Weld-O-Let around the weld area. Many ARGCO variations are specifically identified as having a chamfered configuration.
Does this replace a grooved tee?
A Weld-O-Let can provide a branch connection directly from a header pipe and may eliminate the need for a conventional tee in applications where a welded branch outlet is permitted by the system design.
Can I use any grooved coupling with the outlet?
Use compatible listed or approved grooved couplings and components with appropriate size and pressure ratings. Verify the complete piping-system requirements before installation.
What should I verify before ordering?
Confirm the desired grooved outlet size, run/header pipe size, selected ARGCO SKU, system pressure, required listings or approvals, and compatibility with the piping system.
