Description
Product Overview
The Supplying Demand BC46 capillary tube is engineered for high‑precision fluid transfer in a variety of scientific and industrial settings. Measuring 12 feet in length, the tube features a .046 inch inner diameter and a .093 inch outer diameter, delivering a tight tolerance that ensures consistent flow rates and minimal leakage. Constructed from solid bronze metal, the tubing combines corrosion resistance with structural rigidity, making it suitable for both indoor laboratory benches and outdoor refrigeration systems. The nominal wall thickness of .047 inches provides added durability without sacrificing flexibility, allowing the tube to be routed through tight spaces and around equipment with ease. Each unit is packaged individually, guaranteeing that the product arrives in pristine condition ready for immediate installation.

Usage
This capillary tube excels in applications where precise temperature control and fluid regulation are critical. It can replace existing capillary lines in domestic refrigerators, commercial refrigeration units, and air‑conditioning systems, delivering reliable performance that extends the life of the equipment. Laboratory technicians also rely on the BC46 for chromatography, gas flow regulation, and micro‑fluidic experiments where exact bore dimensions are essential. The tube’s bronze composition tolerates a wide temperature range, making it appropriate for cryogenic processes as well as high‑temperature heat exchangers. Whether you are retrofitting an older appliance or outfitting a new research rig, the BC46 provides a versatile solution that integrates seamlessly with standard fittings and connectors.

FAQ
What equipment is the BC46 capillary tube compatible with?
The BC46 is designed to work with most standard refrigeration and air‑conditioning units that use capillary tubes of similar dimensions. It is also suitable for laboratory apparatus requiring a .046 inch inner diameter, such as gas chromatography columns and micro‑fluidic devices.
How do I install the capillary tube safely?
Begin by depressurizing the system and removing the old tube. Cut the new BC46 to the required length if necessary, ensuring a clean, straight cut. Attach the tube to the appropriate fittings using a secure clamp or compression fitting, then re‑pressurize the system and check for leaks.
Is the bronze material safe for food‑grade applications?
While bronze offers excellent durability, it is not certified for direct food contact. For food‑grade refrigeration systems, we recommend using a tube specifically labeled as food‑safe. The BC46 is ideal for non‑food applications such as industrial cooling, scientific research, and general HVAC use.
Can I use the BC46 in cryogenic environments?
Yes, the bronze alloy maintains its structural integrity at very low temperatures, making the BC46 suitable for cryogenic applications where precise fluid control is required.
What warranty coverage does the product include?
The BC46 comes with a 30‑day return policy for unopened items and a 90‑day limited manufacturer’s warranty covering defects in material and workmanship when used with compatible equipment.
