HVAC Service Kit Contents

The DNBeffulgent SEW1933 set supplies twelve pieces for air-conditioning maintenance. It includes a dual-head valve core tool, two curved wrenches, one straight wrench, three hex adapters covering four sizes, twenty valve cores, two brass nuts, an adaptor cord and five alligator-clip test leads.

Technicians Servicing Standard Systems

The kit suits HVAC professionals working on R22, R12, R407, R410, R404 and R32 installations. It is not intended for automotive air-conditioning repairs. Buyers who need car-specific fittings or a larger assortment of wrench sizes should look at a different package.

Valve Core Tool With Brass Adapter

The dual-head remover and installer tool fits both 1/4 inch and 5/16 inch ports and comes with a brass adapter for R410 and R32 systems. This single component determines whether the set matches the refrigerant equipment you service.

Questions about this item

How do I confirm the valve core remover works with R410 refrigerant after setup?

Attach the dual-head tool to a 1/4" or 5/16" service port on an R410 system; the brass adapter seats without leakage and the core removes cleanly, confirming correct operation.

What items are included in the 12-piece kit and what must I supply separately?

The box contains 1 dual-head valve core tool, 1 valve core tool with brass adapter for R410/R32, 2 curved wrenches, 1 straight wrench, 3 hex adapters covering 1/4", 3/8", 3/16", 5/16", 20 valve cores, 2 brass nuts, 10 alligator clips and 1 HVAC adapter cord; no separate purchases are required for the listed tasks.

Which hex adapter size matches a 5/16" service valve on my unit?

Use the 5/16" hex adapter from the three-piece adapter set; it fits the 5/16" ratchet wrench sizes supplied in the kit.
