HVAC Fittings, Valves & Service Tools – C&D Valve for Aussie HVAC Pros

When you’re chasing down a leak or swapping a valve core on a hot roof, you don’t want to be fighting cheap fittings. This collection brings together C&D Valve fittings, caps and service tools so you can get reliable, repeatable seals on refrigeration and air conditioning systems across Australia.

C&D has specialised in access fittings, cores, couplers and service valves for decades, and their gear is widely used by HVAC wholesalers and technicians for day-to-day service work. Paired with good maintenance practices, quality fittings and valve tools help cut down on refrigerant leaks — a key focus of Australian regulators because leaks drive up energy use and greenhouse gas emissions.

Important: Any work that could release refrigerant — including opening service ports, changing valve cores or installing access valves — must be carried out by a technician with a valid Refrigerant Handling Licence under the Australian ARCtick scheme.

What You’ll Find in This C&D Valve Collection

This collection is focused on the fittings and small tools that keep systems tight, serviceable and compliant:

  • Access fittings & copper tube access valves – for adding safe service points to sealed systems, with options in bulk packs and kits for workshop stock.
  • Adaptors, couplers & ball valves – to match different hose sizes, port threads and service configurations, including straight ball valves for 1/4" SAE connections.
  • Valve cores, caps & core containers – including core assortments with integrated core-wrench tubes, weather-resistant caps and brass core storage pots to keep everything organised.
  • Core depressors & service valve accessories – thumbscrew core depressors and accessories that let you control flow through hoses and manifolds while protecting valve seats.
  • Service kits & pull-through tools – access fitting service kits that bundle cores, caps and fittings for field repairs on domestic and light commercial equipment.

For more general valve gear, you can also browse the wider HVAC Shop Valve collection and the Hand Tools collection for manifolds, torque wrenches and related tools.

Precision Valve Core Tools: Torque Drivers & Removers

Correctly torqued cores and caps are essential for leak-free systems, and current Refrigerant Handling Codes of Practice specify that Schrader valve cores must be tightened to manufacturer torque using purpose-designed tools.

Pair these with a Mastercool valve core remover/installer to pull cores under pressure and maximise flow during evacuation and recovery.

Why Quality Fittings Matter for Energy, Leaks & Compliance

Australian government research shows that installation faults and poor maintenance — including refrigerant leaks — can significantly increase energy use and emissions in both residential and commercial HVAC systems. Using properly rated fittings, torque tools and service valves helps you to:

  • Reduce the risk of slow refrigerant leaks at cores and access points
  • Support compliance with ARCtick and Refrigerant Handling Codes of Practice
  • Protect your customers from higher running costs due to undercharged or overcharged systems
  • Reduce call-backs and repeat leak investigations

For any work that may release refrigerant, technicians must hold the relevant Refrigerant Handling Licence under the ARCtick scheme — it’s a legal requirement across all Australian states and territories.

How This Collection Fits into Your Broader Kit

  • Pair access valves and cores with Flaring & Swaging Kits when you’re adding new service points to copper pipework.
  • Combine fittings with HVAC Service Tools like manifolds, vacuum pumps and leak detectors for full system commissioning and repair.
  • Use HVAC Hand Tools such as ratchet wrenches and tube cutters for tightening flare nuts and prepping copper lines.

FAQ: HVAC Fittings, Valves & Service Tools (C&D Brand)

1. What type of systems are these C&D fittings and valve tools designed for?

These fittings and tools are intended for refrigeration and air conditioning systems that use standard service ports and Schrader-type access valves — including splits, VRF/VRV systems, refrigerated cabinets and small commercial plant. Always confirm pressure rating and refrigerant compatibility in the individual product specs before use, especially with A2L and A3 refrigerants.

2. Do I need a Refrigerant Handling Licence to use these products?

If there’s any risk of releasing fluorocarbon refrigerant while you work — for example when opening a service valve, changing a core or installing an access fitting — the work must be performed by a person with an ARCtick Refrigerant Handling Licence. Homeowners can purchase fittings and tools, but refrigerant work should be left to licensed technicians for legal, environmental and safety reasons.

3. What’s the difference between an access fitting, a core depressor and a service valve tool?

An access fitting or copper tube access valve is a small fitting brazed or clamped into the line to add a service point. A core depressor is a hose-end fitting that pushes down on the Schrader core so refrigerant can flow through your hoses or manifold. Service valve tools, including torque drivers and core removers, are specialised tools that remove, replace or correctly torque the valve cores and caps.

4. How do I minimise refrigerant leaks when working on valve cores and caps?

Use purpose-designed torque drivers set to manufacturer specifications, remove cores before brazing where required, replace worn caps and O-rings with quality parts, and perform leak checks after service using approved methods. Following Australian Refrigerant Handling Codes of Practice and ARCtick guidance is essential.

5. Are these C&D fittings suitable for R32 and other A2L refrigerants?

Many modern fittings and caps are suitable for A2L refrigerants such as R32, but you should always verify this in the specific product documentation and follow any additional safety and ventilation requirements for flammable refrigerants. When in doubt, consult the manufacturer and current Australian refrigerant handling codes.
