-
Precision 3/16″ Stem: Specifically sized for small-diameter copper tubing commonly found in domestic refrigerators, water dispensers, and specialized laboratory cooling equipment.
-
Universal 1/4″ SAE Flare: The service head is a standard 1/4″ male flare, ensuring full compatibility with your existing manifold gauges and charging hoses.
-
Durable Brass Cap: Each valve includes a knurled brass cap with an internal gasket for a secondary seal and a built-in tool for easy valve core removal.
-
High-Pressure Reliability: Rated for modern high-pressure refrigerants, ensuring a secure seal under the demanding conditions of R134a, R600a, and R410A systems.
-
Easy Brazing: The extended copper tail allows you to apply heat for brazing while keeping the sensitive valve body cool.
Applications:
-
Domestic Refrigeration: Ideal for adding a service port to fridges and freezers using 3/16″ tubing.
-
Water Dispensers: Used for maintenance and gas recharging in compact bottled water coolers.
-
Capillary Line Access: Perfect for systems where standard 1/4″ valves are too large for the existing pipework.

Market Insight: In local markets like Ebute-metta or Ladipo, finding the specific 3/16″ size can be harder than the standard 1/4″. Elins Nigeria stocks these specifically for technicians who want a professional fit without having to “force” a larger valve onto a small pipe
Technical Warning: Because 3/16″ tubing is very thin, it heats up extremely fast.
Elins Nigeria Advice: You MUST remove the valve core before brazing. Use a damp cloth to wrap the brass head of the valve to act as a heat sink, preventing the internal seat from warping while you braze the copper stem.
