Midwest Fasteners 66565 3/8"-24 x 7/16" Brass Fine Thread Bleeder Cap

Midwest Fasteners 66565 3/8"-24 x 7/16" Brass Fine Thread Bleeder Cap

The Midwest Fasteners 66565 is a 3/8"-24 x 7/16" brass bleeder cap machined with a fine thread for a precise, leak-resistant seal on small-diameter fittings and bleed points. Solid brass construction gives this cap natural corrosion resistance, making it a dependable choice anywhere a compact threaded cap needs to hold up against moisture and repeated handling. The 3/8"-24 fine thread pitch matches common bleeder valve and fitting applications where a standard coarse-thread cap won't seat correctly, and the 7/16" overall length keeps the cap low-profile once installed. Whether you're servicing hydraulic lines, air fittings, or other small threaded ports, this brass cap is sized and threaded to provide a secure, reusable closure.
