Timsec Refrigerant Charging Valve Set 2-Pc (Blue 1/4 & Red 5/16) Low-Loss Brass, Top-Mount Flow Control

Timsec 2-piece brass refrigerant charging valve set is a low-loss, adjustable flow solution for R12/R22 (1/4") and R410 (5/16") AC service connections.

This compact pair of charging adapters combines durable brass construction and a top-mounted ball valve to let technicians control refrigerant flow during service with minimal loss. Color-coded fittings make size identification quick, and the threaded male-to-female ends fit standard charging hoses and manifolds used across common residential and commercial systems.

How do these valves reduce refrigerant loss during servicing?

The integrated flow-control ball valve permits gradual opening and precise metering, which prevents sudden sprays and wasted refrigerant. Low-loss design and solid brass threads maintain a secure seal under pressure, lowering the chance of fugitive emissions while you connect or disconnect.

• Top-mounted adjustable flow control for incremental opening
• Brass construction resists wear and preserves thread seal
• Compact profile reduces exposed port volume during hookups

Will these adapters work with my R12, R22 or R410A gauges and hoses?

Yes — the blue adapter is configured as 1/4" male to 1/4" female for R12 and R22 service ports, while the red adapter uses a 1/4" male to 5/16" female for R410A systems. They are made to mate with the common hose and manifold fittings used in HVAC maintenance.

• Blue adapter: 1/4" male to 1/4" female — compatible with R12/R22 tooling
• Red adapter: 1/4" male to 5/16" female — built for R410 service connections
• Works with standard charging hoses and manifold gauges

What build quality and safety features do these charging valves offer?

Manufactured from solid brass, the valves provide strong mechanical resistance and corrosion protection in typical refrigeration environments. The ball valve mechanism and knurled adjustment allow safe, controlled flow to help prevent skin or equipment contact with refrigerant under pressure.

• Durable brass body for longevity and corrosion resistance
• Ball valve for reliable shutoff and precise flow control
• Color-coded bodies for quick, error-reducing identification

How easy is installation and everyday use on the job?

Installation is straightforward: thread the adapter onto your hose or manifold, align the correct size to the service port, and use the top knob to regulate flow. The compact, hand-friendly form and clear color coding make swapping between refrigerants quick and mistake-resistant during busy service calls.

• Simple screw-on installation to hoses and manifolds
• Knurled control knob for one-handed adjustments
• Color coding speeds selection and reduces connection errors

Who is this for: HVAC technicians, refrigeration service professionals, and experienced DIYers who work with R12, R22, or R410 systems and need compact, low-loss adapters for charging and diagnostic tasks. These Timsec brass valves are suited for routine maintenance, leak checks, and controlled refrigerant transfer where durability, tight seals, and adjustable flow are priorities.
