Hygienic Fittings

In a hygienic process line, valves are only as clean as the connections around them. A rough joint or a trapped gap can hold product and allow bacteria to grow. 4ma Valves Automation supplies stainless steel hygienic fittings with smooth, crevice-free bores that connect pipes, tanks and valves securely and come apart quickly for cleaning.

Our fittings work with our sanitary valves and are used across pharmaceutical, food, dairy, beverage, cosmetic and chemical plants.

Types of Hygienic Fittings by 4ma

• Tri Clover Clamps: Quick-release clamps in single pin, double pin and heavy duty types that hold two ferrules and a gasket together for a leak-proof joint.
• SMS Union Type: Crevice-free union fittings built to the SMS 1145 standard, ideal where pipe sections must be removed often.
• Ferrule Pipe Connection: Weld-end ferrules, in short, long and instrumentation types, that mate with tri-clamps on pipes, tanks and equipment.
• Gaskets: EPDM, silicone, PTFE and Viton gaskets that seal clamped, union and flanged connections.
• Sight Glass: Straight, union and tri-clamp mounted sight glasses that let operators watch flow, colour and clarity inside a line.
• Air Header: A stainless steel manifold that distributes compressed air from one inlet to several pneumatic outlets.

How Hygienic Fittings Connect Your Process Line

A tri clamp joint uses two matching ferrules with a gasket between them, pulled together by a clamp that is tightened by hand. An SMS union does the same job with a slotted nut that compresses the seal, and it lets you remove one pipe section without disturbing the pipework on either side. Sight glasses sit in the line so operators can check flow at a glance, while an air header feeds compressed air to the actuators and instruments along the line.

Because every joint can be opened without special tools, cleaning, inspection and gasket changes are quick, which keeps downtime low in plants that run frequent CIP cycles.
