3/8 inch Brass Compression Tee OD x OD x OD

3/8 inch Brass Compression Tee – Manufactured for Precision and Durability

The 3/8 inch Brass Compression Tee is designed for branch line connections in soft copper, aluminum, or plastic tubing systems. Engineered for dependable service under varying conditions, this tee provides a mechanical, metal-to-metal seal without the need for soldering or welding, making it ideal for potable water systems and instrumentation lines.

This fitting is manufactured from lead-free brass and complies with current potable water regulations. Each component is machined to tight tolerances to ensure a consistent, secure seal when properly installed with standard compression nuts and sleeves. Ideal for service, repair, or retrofit work, it enables fast installation while maintaining long-term reliability.

Key Features

• Material: Lead-free forged brass – corrosion resistant and code-compliant
• Size: 3/8 inch OD tube (all three ends)
• Connection Type: Compression x Compression x Compression
• Design Standard: Meets ANSI/NSF 61 and ANSI/NSF 372 for potable water applications
• Application: Water distribution, air lines, and select gas service (verify local code allowances)

Performance Characteristics

• Withstands typical residential and commercial working pressures when properly installed
• Rated for use in temperatures up to 250°F depending on tubing compatibility
• All-brass body ensures mechanical strength and impact resistance

Installation Guidelines

Installation requires no heat. To install, insert tubing fully into the fitting, slide the ferrule and nut into position, and tighten per manufacturer-recommended torque. Use of thread sealant is not required on compression threads. For critical systems, hydrostatic testing is recommended post-installation.

Applications

• Potable water lines in residential or commercial buildings
• Branch lines in closed-loop hydronic heating systems (with compatible materials)
• Refrigerant and compressed air systems (verify pressure compatibility)
• Low-pressure gas distribution (as permitted by local code)

Technical Insight

Compression fittings are a standard method for joining tubing where flame-free assembly is required or preferred. Proper alignment and uniform tightening of compression nuts are essential to prevent weeping or full-line leaks. Brass construction offers excellent compatibility with copper and PEX systems when using the appropriate inserts and sleeves.

The 3/8 inch Brass Compression Tee is a trusted solution for licensed professionals requiring fast, code-compliant fittings with a proven service history. Its precision-machined components support long-term system performance while reducing rework and installation time on site.
