Vacuum Mart Division Overview
The Vacuum Mart™ Division has been delivering quality vacuum products to our customers for decades. With more than 14,000 different components for every type of vacuum environment, The Kurt J. Lesker Company® (KJLC®) provides the very building blocks of the industry. We maintain the largest inventory of vacuum products available anywhere, so no matter the need, finding your part at KJLC is a simple, straight forward process from start to finish. KJLC has the most comprehensive inventory in the industry strategically located in our global distribution centers, providing the benefit of “buying locally” from a global supplier. Let us provide streamlined solutions to your complex supply chain and logistic issues.
Specifically, Lesker offers the widest selection of internationally compatible flanged components, feedthroughs, valves, and components, along with a wide range of vacuum pumps, gauging, and vacuum fluids, from leading manufacturers (including KJLC).
Our Featured Products:
KJLC produces more than 1,200 electrical, liquid and gas, motion and optical feedthroughs in a variety of terminations, maximum voltages, and current carrying capacities. A cross-reference table with the part number of two OEMs followed by the equivalent KJLC part number has been provided to help customers select the right part, but as with any product in our catalog, our experienced customer service representatives would be more than happy to assist you. All feedthroughs can be purchased on our website or by contacting our sales department. Many are available for immediate or short term shipping.Learn More
KJLC supplies a complete range of flanges and flanged components such as nipples, elbows, tees, crosses, flex bellows, glass-metal seals, quick couplings, viewports, etc. in all standard vacuum flange systems. KJLC also provides copper gaskets and o-ring gaskets, nut/bolt hardware, tube fittings, gaskets, and vacuum couplings, many of which are available for immediate shipment to eliminate downtime in your production line or research facility.Learn More
The Kurt J. Lesker Company supplies valve solutions for semiconductor processes, industrial vacuum, HV, UHV, and R&D applications, We have the most diverse offering of valve types including: automated conductance control; rectangular and circular gate valves; and door, angle, inline and butterfly valves—many available in both stainless steel and aluminum materials.Learn More
KJLC features multiple devices required for sample manipulation: motion feedthroughs, sample transfer, translation devices, XYZ manipulation, Z-only manipulation, sample rotation, rotary drives, linear drives, and wobble sticks, each helping to mechanically move an object inside a vacuum chamber. Such devices provide precise, repeatable movement or coarse positioning using rotary motion, linear motion, or a combination of both.Learn More
KJLC has a history of over 40 years experience manufacturing hydrocarbon vacuum fluids, greases and lubricants of all grades and viscosities. We recently introduced our new semi-synthetic hydrocarbon oil with superior chemical stability and performance. An anti-oxidation additive extends the useful life of the oil, which, with its low vapor pressure, makes this oil the ideal choice for a variety of applications. Another highlight in this segment is our exclusive partnership with Solvay Specialty Polymers, bringing their successful Fomblin® and Galden® fluids and greases to our stable of top quality oils.Learn More
KJLC makes it easy to find the right product. Navigate the online menu to shop by pump type, technology or manufacturer to access the most comprehensive range of vacuum pumps available from any single supplier. We proudly represent only the finest pump manufacturers in the world. Since some customers shop by 'brand loyalty' while others choose on price/performance alone, we have listed our pumps for easy access using either approach.Learn More
The Vacuum Mart Division offers a full range of traps, filters, and abatement systems required to protect the vacuum chamber from vapors produced by the pumps. These devices also protect the pumps from gases and particulates originating in the chamber, and protect people and the atmosphere from materials in both pumps and chamber. Customers can select foreline traps, system traps, mist eliminators, oil filtration units, and complete exhaust gas abatement systems, as well as a reclaim service for expensive vacuum fluids trapped in contaminated oil filters.Learn More
KJLC offers a full line of gauges and gauge controllers, including convection, thermocouple (T/C), Pirani, diaphragm and capacitance manometers, hot and cold cathode gauges,leak detectors, and all ancillary inlet systems, replacement parts, and filaments. Most items can be purchased online, including those with a complex option list, since KJLC features 'configurators' to help select the exact option list and automatically build the part number and price.Learn More
Because modern vacuum processes require regulated gas flows, calibrated helium leaks, cooling water, liquid nitrogen, compressed air for pneumatic valve operations, and other considerations, KJLC’s Gas/Liquid Management line carries all necessary valves, flow regulators, plastic tubing, and compressed air fittings.Learn More
