The cushion lining isolates the tube from vibration and prevents surface marring, making it well suited for copper, aluminum, or plastic tubing runs where contact noise and abrasion are concerns. Rated at a 150-pound load capacity, the QC34 accepts 2-1\/8-inch outside diameter tubing and mounts to a 3\/8-inch rod. The polyamide construction resists corrosion and handles moderate temperature ranges without becoming brittle. The clamp ships as an individual unit at 0.03 pounds.\u003c\/p\u003e\n\u003cp\u003eCushion clamps of this type are commonly used in refrigeration line sets, HVAC suction and liquid line support, compressed air distribution, hydraulic tubing runs, and general industrial pipe support applications. The 2-1\/8-inch tube size corresponds to standard ACR tubing used in commercial refrigeration and larger residential HVAC systems. Installation is typically performed by HVAC technicians, refrigeration mechanics, pipefitters, or plumbers working on overhead or wall-mounted tube runs that require vibration isolation and secure mechanical support.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAccepts 2-1\/8-inch outside diameter tubing for ACR and general piping applications\u003c\/li\u003e\n  \u003cli\u003ePolyamide construction provides corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eCushion lining absorbs vibration and protects tube surface from abrasion\u003c\/li\u003e\n  \u003cli\u003e150-pound load capacity for reliable tube support\u003c\/li\u003e\n  \u003cli\u003eMounts to 3\/8-inch threaded or smooth rod\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.03 pounds for easy handling during overhead installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation cushion clamp for 2-1\/8-inch outside diameter tubing supported on 3\/8-inch rod in HVAC, refrigeration, plumbing, and industrial piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, refrigeration mechanics, or pipefitters. Isolate or depressurize the tubing system before repositioning or replacing existing clamps. Ensure the rod diameter matches the 3\/8-inch specification before mounting.
