Hey, if you're tired of messing with threaded connections and air leaks, this 96-piece quick connect fitting kit is a lifesaver for your shop. It's got pretty much every connector you'd need: 25 straight push connectors, 10 ninety-degree elbows, 8 straight tube unions, 6 tube tees, 4 elbows with NPT threads, 28 cap plugs, and 1 pipe plug. The sizes cover all the common ones: 1/4\, 3/16\, 5/32\, 3/8\, 1/8\, 1/2\, and 5/8\. They're made from strong Polybutylene Terephthalate (PBT) plastic with stainless steel locking claws and good steel washers, so they hold up under pressure—rated for working pressures up to 145 PSI (that's about 0.9 MPa) and temperatures from 32°F to 140°F. They work great with PU, PA, PE, or PVC tubes. Perfect for automotive air lines, industrial setups, trailer brake connections, manufacturing lines, or even fixing up lawn equipment. Everything comes in one organized set, so you're not running to the store mid-project. We stand by the quality, so if anything's not right, just reach out and we'll sort it out for you.
