Air conditioning plastic nuts

Air conditioning plastic nuts are lightweight seals for connecting copper pipes in air conditioners. Made from high-strength engineering plastic, they are compatible with copper pipes of specific diameters. They utilize an internal sealing ring to seal the refrigerant, preventing metal corrosion and the risk of condensed water conduction.
They are suitable for use in indoor unit piping for residential air conditioners and in non-high-voltage connections for small refrigeration equipment.
They are manufactured using weather-resistant plastic, injection-molded, and seal-tested, and are compatible with refrigerants R22/R410A.
Our service includes selection guidance. Advantages include lightweight, corrosion-resistant design, low cost, easy installation, and compatibility with non-high-voltage applications.
Air conditioning plastic nuts are lightweight, corrosion-resistant connectors for connecting copper pipes in air conditioners in non-high-voltage applications. Their core advantages are "corrosion resistance and safety + low-cost compatibility." They are precision-injected and feature an internal refrigerant-resistant nitrile rubber sealing ring (compatible with mainstream refrigerants such as R22 and R410A). Once tightened, they fit snugly into the copper pipe flare. The plastic material not only eliminates the risk of condensed water conduction from metal sodium connectors but also resists rust in humid environments, extending their service life. Weighing only one-third the weight of brass ferrites of the same specification, they reduce the load on piping. Their smooth, burr-free surface prevents scratches on hands or copper pipes during installation. They cover common pipe diameters for home air conditioners, such as 6mm and 9.52mm, and some models feature anti-misinstallation clips to prevent reverse installation. Costing less than metal ferrites, they are suitable for bulk purchases. Applications include non-high-pressure connections between indoor units and connecting pipes for wall-mounted or cabinet air conditioners, pipe sealing for small dehumidifiers and mobile air conditioners, and replacement of indoor pipe connectors during air conditioner after-sales repairs. They are particularly suitable for humid indoor environments or where safety is a concern, meeting sealing requirements while balancing safety and cost advantages.
