Copper Dimple Stop Coupling for 1-1/2" Lines

This sweat fitting joins two 1-1/2 inch copper tubes in a straight line. It suits potable water, air and gas distribution systems where a permanent, leak-tight joint is required. The dimple stop centres each tube automatically during assembly.

Thermals, Noise and Power Draw

The wrot copper body handles continuous temperatures up to 400 degrees F and pressures up to 408 psi at 100 degrees F. As a passive component it generates no noise and draws no power. Copper construction resists corrosion and maintains strength through thermal cycling.

Build Integration

The coupling accepts 1-1/2 inch copper tube on both ends with a 1 5/8 inch outer diameter. No extra fittings, gaskets or threading are needed beyond standard solder and flux. It frees installers from measuring insertion depth because the internal dimple provides a positive stop.

Questions about this item

How is the 1-1/2" copper dimple stop coupling sweated onto the tube, and what step causes leaks?

Clean both tube ends and the cup interiors, apply flux, insert tubes fully until they hit the internal dimple stops, then heat evenly and feed solder until the joint rings completely; skipping full insertion past the dimple leaves a gap that leaks.

What maintenance or replacement will this wrot copper coupling need over time?

Wrot copper resists corrosion in potable water and air systems, so no routine maintenance is required; replace only if a joint shows visible green crust, pitting, or a pressure test reveals a weep at the sweat connection.

Which limit appears first during sustained high-temperature use — the 408 psi pressure rating or the 400 °F temperature rating?

The 400 °F maximum operating temperature is the first hard limit; above it the copper softens and the pressure rating no longer applies, so system design must keep fluid temperature at or below 400 °F.
