-
Precision ACR Sizing: Sized at 1/2″ O.D. to match the suction and discharge lines of small commercial refrigeration units and specialized cooling systems.
-
Oil Return Engineering: The radius is optimized to maintain refrigerant velocity in small lines, effectively “lifting” oil up vertical pipes to keep the compressor lubricated.
-
Dehydrated & Sealed: Each unit is factory-cleaned and sealed to ensure the interior remains free from moisture and contaminants, making it safe for sensitive refrigerant circuits.
-
Vibration Resistance: The rigid, high-purity copper construction handles the constant mechanical pulses of small reciprocating compressors far better than plastic alternatives.
-
Solder-Ready Sockets: Features precision-machined female ends for a fast, airtight capillary fit using silver-bearing brazing alloys.
Applications:
-
Small Suction Risers: Essential for oil management in small refrigeration systems with vertical pipe runs.
-
Specialized Condensate Drainage: A premium alternative for compact AC units or laboratory equipment where space is limited.
-
Commercial Bottle Coolers: Ideal for oil traps in reach-in beverage chillers and small display cases.

Technical Warning: Always remove any debris or factory caps before brazing.
Elins Nigeria Advice: Because 1/2″ copper is relatively thin, it heats up very quickly. Use a small, focused flame and a high-silver content brazing rod to ensure a strong joint without melting through the pipe wall.
Warning: If using this in a suction line, always purge with dry nitrogen during brazing to prevent internal scaling.
