Air Tech master A/C O-ring kit
The complete automotive A/C O-ring set — 160 part numbers and 936 pieces of the O-rings you reach for across GM, Ford, Toyota, Honda, and more, all organized in a labeled case. It covers orifice-tube, captive, pad-mount, hose-fitting, and pressure-switch O-rings in both metric and standard sizes, from a tiny 4.39 mm ID up to 36 mm ID.
One case, every O-ring
Stop losing jobs to a missing O-ring
Truly complete
160 part numbers cover the A/C O-rings used across the major makes — the right seal is in the box instead of on back-order.
Every application
Orifice-tube, captive, pad-mount, standard hose-fitting, and pressure-switch O-rings for automotive, HVAC, and industrial sealing.
Metric & standard
A full range of metric and standard sizes, from a small 4.39 mm ID up to a large 36 mm ID.
10 of each
Every part number comes in a 10-count so you’ve got backups on hand for repeat repairs.
Organized case
Packaged in a labeled, compartmented case for fast identification and easy storage on the bench.
Refillable
Reorder the size ranges below — or individual O-rings — to keep the case topped up.
