HENGSEN Copper P-Trap Oil Return Bend for Refrigeration
Description
Product Overview
HENGSEN Copper P-Traps are preformed oil return bends for refrigeration and air-conditioning pipework. The copper fitting provides a ready-made P-shaped section for installations where the piping design requires an oil trap.
Available in eight listed connection sizes from 15.88 to 54 mm, with wall thicknesses from 1.0 to 1.8 mm, this range allows you to select the fitting that matches your project specification.
In correctly designed suction piping, a P-trap helps refrigerant flow carry oil up a vertical riser toward the compressor. Fitting size and placement should follow the equipment manufacturer’s piping requirements.
Key Features
- Preformed P-Shaped Bend: Provides the trap geometry as a ready-made fitting for installation into the specified pipe layout.
- Copper Construction: Copper body with socket ends for connection to compatible copper pipework.
- Eight Size Options: Listed connection sizes include 15.88, 19, 22.23, 25.4, 28.58, 35, 41.28 and 54 mm.
- Specified Wall Thickness: Each size is paired with its listed wall thickness to make ordering clear.
- Oil-Return Piping Component: For use at locations where the refrigeration system design calls for a P-trap.

Applications
For refrigeration and air-conditioning projects requiring a copper oil return bend, including suction riser arrangements in cold storage and commercial refrigeration installations. Application suitability depends on the system design and operating conditions.
Selection & Installation
Select the required connection size and wall thickness from the table. Check the available installation space against the drawing for the selected fitting. Have the connection method, pressure requirements and refrigerant compatibility confirmed for the intended system before installation.
Trap location and orientation should follow the equipment manufacturer’s piping layout. Correct line sizing and refrigerant velocity remain essential to oil return.
