Murray Corporation manufactures the Keystone KSC series of mechanical and stainless pinch clamps, engineered for secure, tamper-resistant connections on small-diameter hoses and tubing. The KSC mechanical design provides reliable clamping performance in applications where a permanent, low-profile connection is required and space is limited.
The Keystone KSC mechanical pinch clamp features a one-piece stainless steel construction with pre-formed ears that are crimped during installation to create a tight, uniform seal around the hose. Unlike welded pinch clamp designs, the KSC mechanical clamp uses a precision-formed mechanical closure that eliminates the heat-affected zone associated with welding, maintaining consistent material properties across the entire clamp body.
This construction method offers several advantages. The mechanical forming process ensures repeatable dimensional accuracy across high-volume production runs. The absence of weld splatter or weld-related surface irregularities means the clamp sits flush against the hose surface for uniform sealing pressure. The stainless steel material provides excellent corrosion resistance for applications involving water, coolant, fuel, and other fluids.
Keystone KSC mechanical pinch clamps are used across a wide range of industries and applications, including automotive fuel lines, emissions systems, and coolant connections, beverage dispensing and food-grade fluid handling, medical and pharmaceutical tubing, HVAC condensate drains and refrigerant lines, small engine fuel systems, and industrial fluid transfer and pneumatic connections.
The low-profile design makes KSC clamps particularly well suited for applications with tight clearance requirements, such as under-hood automotive assemblies and compact equipment enclosures.
KSC mechanical pinch clamps are installed using Murray's industrial pinch clamp tools, which apply the precise closing force needed to compress the ears and achieve a secure seal. Proper tool selection and calibration ensure consistent clamping performance across production runs. Once installed, the clamp provides a permanent, tamper-resistant connection that does not loosen over time due to vibration or thermal cycling.
Murray manufactures the Keystone KSC series in a range of sizes to accommodate common small-diameter hose and tubing dimensions. Stainless steel construction is standard. Custom sizes and material options are available for specialized applications. Contact Murray Corporation or request a quote to discuss your Keystone KSC pinch clamp requirements.
