ASTM B819 Medical Copper Fittings are specifically manufacture to be used in the medical gas and vacuum systems where they provide clean, reliable and contamination free passage of gas. These copper fittings are made of high-purity phosphorus-deoxidized copper which is degreased and clean to medical standards. They offer joints free of leakages and service life in oxygen lines and other medical gas lines. They are fully in line with the standard ASTM B819 and ASME B16.22 and are suitable in the hospital and health distribution gas system.
ASTM B819 Medical Copper Fittings – Types
ASTM B819 Medical Copper Fittings comes in a great variety of types to meet most medical gas pipeline effects. Products of this range are Tees, Elbows, 90deg and 45deg, Couplings, Reducers, End Caps, Y Bends, U Bends, Unions, and Cross Tees. All the fittings are created to deliver safe, leak-free joints and flowing gas in hospital gas, and vacuum systems. These copper fittings are produced using the highest purity of copper in accordance with ASTM B819 and ASME B16.22 standards thus are reliable and clean and can perform over time within the hospital and healthcare gas distribution systems.

FAQ (Frequently Asked Questions)
Are ASTM B819 medical copper fittings corrosion resistant?
Yes. Copper naturally resists corrosion, making these fittings highly durable and suitable for long-term use in medical gas pipeline systems.
How are ASTM B819 medical copper fittings joined?
They are typically joined by brazing using approved filler metals. During brazing, a nitrogen purge is recommended to prevent oxidation inside the piping system.
