  • Product typeDrain Components
  • Wrot copper construction resists corrosion for long service life
  • Coupling without stop allows continuous pipe runs without interruption
  • C x C solder connection creates strong leak-resistant joints
  • Rated to 582 psi at 100°F for high-pressure confidence
  • Operates from -20°F to 400°F across wide temperature range

Copper Coupling for 3/4 in Tubing

This copper coupling connects two 3/4 in nominal tubes with a C x C fitting connection. It is suited for plumbing professionals and DIY installers joining copper pipe in residential or commercial water systems. The wrot copper construction meets ASME/ANSI B16.22 standards for reliable performance.

Wrot Copper Build with No Internal Stop

The coupling is made from wrot copper and has no internal stop, allowing tubes to slide fully through for flexible positioning during assembly. The smooth bore reduces turbulence and supports a maximum pressure of 582 psi at 100 degrees F. It withstands temperatures from -20 to 400 degrees F.

Replaces Damaged or Leaking Copper Joints

This fitting upgrades ageing solder joints or replaces cracked couplings in existing copper lines. The jump is worth it when a permanent, code-compliant repair is needed and the installer prefers a stop-free design for easier alignment. It is not for buyers who need a built-in stop to limit insertion depth.
