The Mastercool 90430 is a 1/4″ FFL × 1/4″ MFL swivel ball valve for fast isolation at the hose end. Add it to manifolds, recovery lines or custom rigs to stop flow with a simple quarter-turn — fair dinkum time saver for Aussie fridgies.

Key Features & Trade Benefits

• 1/4″ FFL × 1/4″ MFL swivel — fits common hoses and service gear; easy orientation without twisting lines.
• Manual lever shut-off — precise, one-hand control for cleaner connect/disconnects and less loss.
• EPA-focused use — place near the hose end to minimise venting during service (no hose supplied for custom setups).
• Brass body, service-ready — built to cop daily site abuse; long life with proper gasket care.
• Swivel design — reduces strain at the connection and helps keep seals happy — too easy on tight installs.

Why This Product Matters

Real-world: on a windy Sydney roof, the tech flicked the valve shut before cracking the fitting — no puff, no mess, straight back to readings. Minutes saved, fewer call-backs. If you’re building a clean, vent-safe setup, this little unit earns its keep. For more options, check our control valves.

Pro Tip

Run a shut-off within ~300 mm of the hose end, then change over tools with the system sealed. Pair it with fresh hose gaskets to keep micro-leaks at bay — she’ll be right.

FAQs

Will it fit my hoses and manifold?
Yes. It’s 1/4″ flare female swivel to 1/4″ flare male — the most common legacy connection.

Is a hose included?
No. It’s supplied as a valve only so you can build custom setups.

Can I use it on R410A/R32 systems?
Many newer hoses/ports are 5/16″; use an appropriate adapter or a 5/16″ valve if required. See our control-valve options.
