1-1/4 in P-Trap for air, gas and potable water

This wrot-copper P-Trap handles air, gases and potable water at up to 439 psi at 100 °F and 400 °F maximum temperature. Sweat cup connections on both ends accept 1-1/4 in copper tube with a 1-3/8 in outer diameter. Model U698 11/4 is supplied new for residential and light-commercial plumbing installations.

Verify tube size, pressure rating

Confirm that your system uses 1-1/4 in copper tube with a 1-3/8 in outer diameter so the cup fittings seat correctly. Check that the 439 psi rating at 100 °F covers your design pressure and that the 400 °F limit exceeds the highest fluid temperature expected. Ensure local plumbing codes permit wrot-copper P-Traps for the intended air, gas or potable-water service before ordering.

Maintains seal and strength under continuous

The wrot-copper body resists deformation when operated continuously at the rated 439 psi and temperatures approaching 400 °F. Sweat joints remain leak-free during sustained thermal cycling because the fitting and tube expand at similar rates. The P-Trap geometry retains its water seal under steady flow, preventing gas or vapour bypass during long operating periods.

Questions about this item

Does the U698 11/4 suction line P-trap include any solder or flux, or must they be purchased separately?

The box contains only the wrot copper P-trap with two cup connections. Solder, flux and any pipe sections are not included and must be sourced separately.

The model shows 1 1/4 in copper tube size on both ends — is there a different capacity version I should consider?

This specific U698 model is built for 1 1/4 in copper tube (1 3/8 in outer diameter) on both sides. No other capacity is offered under this part number.

The spec lists 439 psi at 100 Degrees F — will that pressure hold when the line runs at higher temperature?

The 439 psi rating applies at 100 Degrees F. The fitting is rated to 400 Degrees F maximum operating temperature, but allowable pressure decreases as temperature rises above the reference point.
