Copper Capillary Lines

Industrial Copper Capillary Lines (⅜” BSP M-F)

Safeguard your monitoring instruments and optimise your system layout with our range of Copper Capillary Lines. These flexible, small-bore copper tubes act as a highly effective thermal barrier and dampening extension, allowing you to remotely mount pressure gauges, switches, and transducers away from high-temperature pipelines, harsh environments, or hard-to-reach process areas.

Equipped with a standard ⅜” BSP Male thread on one end and a matching ⅜” BSP Female swivel connection on the other, these lines allow for quick, inline installation without twisting the capillary tube. The fine internal bore effectively cushions rapid pressure spikes and fluid pulsations, keeping your gauge needles steady for easy, accurate readings while significantly extending the operational lifespan of your equipment.

Key Features & Benefits

• Instrument Protection: Isolates sensitive gauge internals from excessive heat and direct system pulsations, minimising the risk of thermal damage or premature calibration drift.
• Remote Mounting Convenience: Allows you to position pressure gauges at eye level or centralise them onto instrument panels for safer, more efficient routine inspections.
• Male-to-Female Connections: Outfitted with universal ⅜” BSP threads (one male, one female swivel) to seamlessly fit into your existing gauge cock or manifold layout.
• High-Quality Copper Tubing: Offers excellent thermal conductivity for cooling media, reliable pressure containment, and the structural flexibility required to route lines around obstacles.
• Four Standard Lengths: Choose from 1m, 2m, 3m, or 5m configurations to perfectly suit your installation footprint.
