Mudder refrigerant adapter kit 35-piece — Brass R32/R454B R410A R134a R1234yf adapters with valve cores & gaskets

Mudder 35-piece refrigerant adapter kit is a brass multi-refrigerant connector set that lets you convert and connect R32, R454B (A2L), R410A, R134a and R1234yf lines to common 1/4" gauge and service ports quickly and reliably.

This comprehensive kit bundles brass adapters, valve cores, gaskets and removal tools engineered for HVAC, mini-split and automotive air conditioning servicing. All components are corrosion-resistant brass or HNBR-compatible materials suited for repeated use on charging hoses, manifolds and refrigerant tanks. The parts list covers the most common thread conversions technicians and advanced DIYers encounter when working across R32/A2L, R410A and R134a/R1234yf systems.

What adapters and tools are included in the Mudder kit?

The kit supplies a broad mix of adapters and service parts so you can convert between popular charging ports without improvisation. It includes dedicated R32/R454B and R410A fittings plus R134a and R1234yf adapters, spare valve cores and all the small seals and washers you need for a secure connection.

• 2 x R32/R454B (1/4" female to 1/4" male reverse thread)
• 2 x R410A (5/16" female to 1/4" male reverse thread)
• 1 x R134a adapter and 1 x R1234yf adapter
• 10 valve cores, 5 valve stem pins, 5 rubber gaskets, 8 washers

How durable and leak-resistant are the parts?

Each brass fitting is machined for mechanical strength and corrosion resistance, and the kit includes HNBR-style gaskets and washers to maintain seals under pressure. Brass resists rust in typical service environments, while the spare valve cores and O-rings help prevent leaks after repeated connects and disconnects.

• Brass construction for corrosion resistance and long life
• Quality gaskets and washers to reduce wear and leakage
• Multiple spare valve cores included for quick replacements

Will this kit work with modern A2L and mixed refrigerant systems?

Yes — the kit explicitly supports A2L-compatible R32 and R454B fittings alongside R410A, R134a and R1234yf adapters. That cross-compatibility makes it useful for technicians working with newer low-GWP refrigerants and older fluorinated systems, reducing the need to carry separate adapter sets.

• Compatible with R32, R454A/B/C, R410A, R134a, R1234yf
• Converts common 1/4" and 5/16" charging ports to 1/4" gauge fittings
• Works with standard manifold and hose sets for HVAC service

How easy is installation and everyday use?

The fittings thread and hand-tighten quickly to create a working seal — no exotic tools required for normal connections. A built-in gasket and included valve core remover speed routine maintenance tasks, and the compact kit fits neatly in a technician bag for on-site calls.

• Hand-tightenable designs for fast connect/disconnect
• Includes valve core remover for expedited servicing
• Small parts and spares organized for field repairs

Who is this for: HVAC installers, refrigeration technicians, mini-split specialists and experienced automotive air-conditioning users who need a versatile, field-ready adapter set. If you service multiple refrigerants or want spare valve cores and seals on hand, this Mudder kit reduces downtime and helps standardize your charging connections across A2L and conventional refrigerant systems.
