Internal ACME Threaded Access Fitting Assemblies

Cosasco ACME Threaded access fittings have internal female ACME Thread that receives either a solid or hollow male ACME threaded plug. The ACME threaded access fittings are advantageous in applications where the process contains solids and debris.

Access Fittings that are mounted bottom-of-line are especially susceptible to solids getting lodged in the threads of the plug assembly. ACME threads have courser threads with a larger pitch and a narrower angle than standard v-threads, preventing the plug assembly from getting jammed in the access fitting due to debris getting caught in between the threads.
