MPI Fittings

Parker MPI™ Fittings are engineered for reliable, leak-free performance in medium-pressure applications. Designed with a single-ferrule mechanical grip, they provide safe and durable connections for tubing in demanding instrumentation and process environments.

Parker MPI™ Fittings are specifically developed to meet the needs of medium-pressure instrumentation systems, combining safety, ease of installation, and robust sealing performance. Their unique one-piece ferrule design provides a strong mechanical hold and gas-tight seal, reducing the risk of leakage under high-pressure and dynamic conditions. Manufactured in corrosion-resistant stainless steel, MPI™ fittings ensure long service life and are fully interchangeable with industry-standard medium-pressure cone-and-thread connections. Ideal for applications in oil & gas, chemical processing, power generation, and test systems, Parker MPI™ Fittings deliver confidence in performance and system integrity.
