Sanitary Fittings, and Clamps

Sanitary Fittings, and Clamps

Cole-Parmer carries a wide variety of sanitary clamp fittings in many sizes, styles and materials for your specific needs. Whether for permanent stainless steel piping systems or for a single-use system requiring a plastic sanitary adapter, Cole-Parmer can provide the sanitary coupling you need for your work. These fittings are standard in many industries, including the food/beverage and biopharmaceutical industries.

Sanitary clamp fittings and sanitary clamp couplings make connections by means of a sanitary clamp. The sanitary fittings each feature a flat circular face with an outer groove made to specific dimensions; see table below for exact face dimensions of common sizes of sanitary couplings up to 3 inches (larger sizes may be available; contact Cole-Parmer for more information). The groove anchors a sanitary gasket that provides a sanitary and secure seal between the two fittings. Holding the entire connection together is the sanitary clamp; the most common design is known as the Tri-Clamp from Alfa Laval Inc., although other styles of clamps are available. Typically the sanitary clamp is stainless steel, but there are also versions available in nylon. The sanitary clamp connection has many benefits, including easy disconnection and replacement of components and an assured sanitary flow path when connected properly. Dependent on size of the connection, the sanitary clamp connection may be rated as high as 2,200 psi at ambient temperature. Typically, the pressure-limiting components in the connection are the clamp and/or the gasket.

Choose from a wide variety of configurations, including reducers, barbed and threaded adapters, elbows, tees, crosses, and caps. Cole-Parmer offers sanitary clamp fittings in stainless steel (both 304 stainless steel and 316 stainless steel) as well as plastics such as PFA, polypropylene, and PVDF. Stainless steel fittings are available to meet ASME-BPE 2002 specifications with 20Ra mechanical and 15Ra electropolished surface finishes. To make complete connections, Cole-Parmer also offers 304L SS sanitary clamps and nylon clamps as well as sanitary gaskets in a variety of materials. All wetted parts meet 3A sanitary standards.
