Rubber Fab offers a variety of hinge clamps for any application. Whether it is single pin sanitary hinge clamps or slotted clamps for spore traps, all of your clamp needs are covered here. Also known as the tri clover clamp, these sanitary clamps work with standard tri clamp fittings, sanitary tri clamp gaskets, and hose fittings/adapters. Let us fit your application with the right clamps and sanitary seals.

Types and comparisons: Common sanitary tri clamp styles include single pin, gold single pin, double pin, high pressure, biological indicator, thermocouple (Smart Gasket), spore trap slotted, tabbed orifice plate, I-Line, and non-metallic. Single pin sanitary clamps are quick to install for general service; double pin sanitary clamps provide added strength and alignment; high-pressure clamps are designed for elevated pressures and critical duty; specialty clamps (indicator, thermocouple, orifice, spore trap) integrate process functions; I-Line hinge clamps mate with I-Line ferrules for heavy-duty pipelines; and non-metallic clamps offer corrosion resistance and lightweight handling. Compared to each other, single pin is fastest for routine use, double pin improves clamping force and rigidity, and high-pressure or squeeze clamp styles maximize sealing force for demanding applications. These options ensure compatibility with tri clamp fittings and the broader sanitary tri clamp ecosystem.

Selection guidance: To select the appropriate sanitary tri clamp based on application requirements, consider pressure rating, temperature, vibration, cleaning frequency, and connected components (ferrule type and size). For low-to-moderate pressure and frequent changeovers, a single pin sanitary clamp is often sufficient. Where thermal cycling or vibration is present, choose a double pin sanitary hinge clamp for added stability. For CIP/SIP conditions and elevated pressures, use high pressure clamps or squeeze clamp styles to maintain a secure joint with your tri clamp fittings. For process monitoring or sampling, select specialty clamps like the Smart Gasket thermocouple clamp or biological indicator clamp. Always pair the clamp with the correct tri clover clamp ferrule size and a compatible tri-clamp gasket to ensure a reliable sanitary seal.

Benefits and use cases of high-pressure and squeeze clamp styles: High-pressure sanitary clamps and squeeze clamp designs deliver higher compressive force on the gasket, improving sealing integrity under pressure spikes, steam sterilization, or pumping surges. These sanitary clamps are ideal for pharmaceutical reactors, high-shear mixing skids, and hot CIP/SIP loops where a standard tri clover clamp might relax. They reduce the risk of microleaks, protect against blow-offs, and maintain alignment of tri clamp fittings during thermal expansion. In short, when demanding conditions meet strict hygienic standards, high-pressure and squeeze styles in the sanitary tri clamp family provide superior performance.

What is a tri-clamp gasket? A tri-clamp gasket (also called a sanitary tri clamp gasket) is the elastomeric or PTFE sealing element compressed between two ferrules by a tri clover clamp. It creates the hygienic seal in a tri clamp connection. Selecting the right gasket material (e.g., EPDM, silicone, FKM, PTFE) depends on chemical compatibility, temperature, and regulatory needs. Proper compression from the sanitary clamps is essential to ensure a smooth, crevice-free seal with your tri clamp fittings.
