1-1/4 inch Stainless Steel Insert Adapter Insert x Male

1-1/4 Inch Stainless Steel Insert Adapter – Insert x Male Thread Connection

The 1-1/4 inch Stainless Steel Insert Adapter provides a transition between barbed (insert) and male threaded pipe connections, commonly used in potable water distribution and pump assemblies. Manufactured from corrosion-resistant stainless steel, this fitting supports high-integrity mechanical connections in both new system layouts and retrofit work.

Material and Performance Considerations

Proper material selection and dimensional consistency are critical for system performance and code compliance. This insert adapter is engineered for use in systems requiring lead-free components and provides the following advantages:

• ✅ Machined for Consistency Manufactured with uniform thread pitch and barb profiles to ensure accurate alignment and sealing under pressure.
• ✅ 304/316 Stainless Steel Construction Provides excellent resistance to scale, chemical exposure, and corrosion, particularly in aggressive water conditions.
• ✅ NSF/ANSI Lead-Free Compliant Suitable for potable water applications under current federal and state regulations.

Application Efficiency and Jobsite Advantages

• ✅ Field Durability Maintains structural integrity in high-humidity or buried installations where galvanized or brass fittings may degrade over time.
• ✅ Fast, Repeatable Installations Threaded and barbed ends support standard assembly practices with mechanical clamps and sealants.
• ✅ Adaptable for Multiple System Types Used in municipal, residential, and agricultural water systems, particularly where corrosion resistance is critical.

Specifications

• Material: Stainless Steel (typically 304 or 316 grade)
• Size: 1-1/4 inch nominal
• Connection Type: Insert (barbed) x Male NPT
• Compliance: Lead-free under NSF/ANSI 61 and 372 standards

Installation Guidelines

Use stainless or approved corrosion-resistant clamps on the insert side with flexible polyethylene or polybutylene tubing. Apply PTFE thread tape or appropriate sealant to the male threads. Ensure thread engagement meets code torque requirements. System pressure testing should follow all regional plumbing codes upon completion.

Common Use Cases

Frequently installed in potable water main connections, well systems, service entrances, and irrigation piping where dissimilar pipe types or flexible tubing require a secure threaded transition. Stainless steel construction makes it suitable for both above-ground and underground applications where long service life is a priority.

Material Performance Note

Stainless steel maintains mechanical strength across a wide range of temperatures and environmental conditions, reducing the risk of fitting degradation in systems with fluctuating pressure or water chemistry.

The 1-1/4 inch Stainless Steel Insert x Male Adapter is a durable solution for pressurized water systems requiring corrosion-resistant, lead-free fittings with code-compliant performance.
