Description
Domestic Wrot Copper Suction Line P-Trap
Domestic wrot copper suction-line P-traps create a formed trap in compatible refrigeration and air-conditioning suction piping. The copper x copper sweat connections allow the trap to be soldered directly into properly sized copper tubing.

How a Suction-Line P-Trap Works
The formed trap is installed in a compatible suction-line layout where required by the refrigeration or air-conditioning system design. In properly engineered installations, the trap can help collect and carry compressor oil through vertical suction risers and support oil return to the compressor.
Important Application Distinction
This product is intended for refrigeration and air-conditioning suction piping. It is not a plumbing drain P-trap and should not be selected for sanitary drainage applications.
Common Applications
Refrigeration Systems
- Commercial refrigeration equipment
- Refrigerated display systems
- Walk-in cooler and freezer systems
- Condensing-unit suction piping
- Refrigeration equipment retrofits
- Approved vertical suction risers
Air-Conditioning Systems
- Split-system air conditioning
- Heat-pump refrigerant piping
- Commercial HVAC systems
- Mechanical-equipment connections
- System maintenance and replacement
- Approved oil-return piping arrangements
Installation Guidance
- Confirm that a suction-line trap is required by the equipment manufacturer or system designer.
- Select the trap that matches the outside diameter of the copper tubing.
- Install the trap in the orientation required by the approved piping design.
- Clean and prepare the copper tube and fitting sockets properly.
- Use approved joining materials and procedures suitable for the refrigerant system.
- Protect nearby valves, seals, insulation, and equipment from excessive heat.
- Purge with dry nitrogen during brazing when required by accepted refrigeration practices.
- Pressure-test and evacuate the completed system according to equipment and code requirements.

Frequently Asked Questions
What is a copper suction-line P-trap used for?
It is installed in compatible refrigeration and air-conditioning suction piping where the approved system design requires a formed trap for oil management and return.
Is this the same as a plumbing drain P-trap?
No. This product is intended for refrigeration and air-conditioning suction piping, not sanitary drainage systems.
Are both connections the same size?
Yes. The trap has equal-size copper sweat connections on both ends.
How do I choose the correct size?
Select the variation that matches the outside diameter and nominal size designation of the copper refrigeration tubing used in the system.
Does every suction line require a P-trap?
No. Trap requirements depend on the equipment manufacturer’s instructions, vertical lift, piping arrangement, refrigerant velocity, compressor requirements, and overall system design.
Where is the trap normally installed?
Its location depends on the approved refrigeration piping design. It may be installed near the base of a vertical suction riser or in another location specified by the equipment manufacturer or system engineer.
Should this fitting be soldered or brazed?
Use the joining method, filler material, purge procedure, and temperature control required by the refrigerant system, applicable codes, and equipment manufacturer.
Who manufactures this suction-line P-trap?
This product is manufactured by Cello Products.
Is this a domestic copper product?
Yes. This product is listed as a domestic wrot copper fitting.
Can this fitting alone guarantee proper oil return?
No. Proper oil return depends on the complete piping design, tube sizing, refrigerant velocity, vertical lift, trap placement, equipment requirements, and operating conditions.
