What it is:   
standardized cooling/air/hydraulic fittings (NPT, quick-couple, push-fit) that enable fast, leak-free connections to manifolds and hoses. 

Typical applications:   
cooling circuits on injection molds, manifold hookups, pneumatic lines for ejectors. 

What it solves:   
speeds maintenance and changeover, prevents coolant/air leaks, and simplifies field servicing. 

Common materials:   
brass, stainless steel, plated steel with elastomer seals. 

Common issues & maintenance:   
seal wear, corrosion, cross-threading — replace O-rings and check torque regularly. 

Selection tips:   
use stainless for corrosive environments, quick-couplers for frequent changeovers, and ensure connector pressure rating matches system specs.
