• Overall Length: 7″ (effective threaded length ~6.5″)
• Threading: MNPT × MNPT — threads on both ends for easy coupling
• Schedule: 40 (standard wall thickness)
• Material: Red Brass (ASTM B43, B687 standards)
• Outside Diameter: 1 3/64″
• Wall Thickness: 0.114″
• Thread Size Designation: ¾″ MNPT
• Operating Temperature Range: –20 °F to 450 °F (approx)
• Maximum Pressure (at temperature): 240 psi
• Applications: Suitable for air, natural gas, oil, potable water, steam services (within temperature limits)
• Certifications / Standards: AB 1953, ANSI B1.20.1, ASTM B43, ASTM B687, NSF 372

Advantages & Use Cases

• Durability & Corrosion Resistance: The red brass construction offers excellent resistance to corrosion, ideal for plumbing environments.
• Threaded Versatility: With male threads on both ends, it easily connects two female-threaded fittings or pipes.
• Standard Wall Strength: Schedule 40 thickness provides a balance between strength and cost for normal pressure systems.
• Wide Application Range: Compatible with water, steam, gas, and oil systems (within pressure and temperature specs).
• Industry Compatibility: Built to standard threading and material specs for interchangeability with other fittings.

Suggested Applications

• Plumbing installation requiring a short run between two female-threaded components
• HVAC systems where red brass is compatible with surrounding materials
• Industrial or mechanical systems with moderate pressure and temperature
• Retrofit or repair tasks in infrastructure piping
