What Checkfluid does

Checkfluid Inc. is a privately held Canadian manufacturer founded in 2001 that designs and produces industrial fluid sampling valves, sampling tubes, and associated hardware for condition-monitoring programs on mechanical equipment. The company's core product portfolio comprises six sampling valve series (KP Pushbutton, KST Series, B Series, L High Flow, LE Mobile Drives, and LP Pushbutton) engineered for pressurized and non-pressurized applications across engines, transmissions, hydraulic systems, gearboxes, and final drives, supplemented by sampling tubes, sight glasses, breather and drain mounts, vacuum pumps, hose assemblies, and consumables such as bottles, tubing, and mailers. Differentiated technologies include zinc-nickel plating providing 5–7x the corrosion resistance of industry standard, a 3D Sight Glass on the LTJ Sight for any-angle oil-level visualization, high-flow valve designs capable of sampling VG 32–VG 1500 viscosity oils without equipment shutdown, and the wireless DPI (Drive Positioning Indicator) for orienting drive axles during service. The company is ISO 9001:2015 registered and holds a complete accessory ecosystem that enables single-vendor procurement for fluid sampling workflows.

The business operates a direct B2B sales motion through its e-commerce-enabled company website, with quote-based pricing (no public price list), phone and email-based sales support, and a catalog-request workflow with PDF downloads segmented by application (General, Engine, Hydraulic, Gearbox Sampling). Customers are operators of heavy equipment, transmission manufacturers and service providers (with named compatibility for Allison, Voith, and ZF Ecolife transmissions), hydraulic system operators, and industrial gearbox and final drive service facilities — primarily in North America, with product compatibility for international thread standards (NPT, BSPP, Metric). Revenue is generated through one-time hardware sales of configured valves plus recurring consumable revenue from disposable sampling tubes, bottles, mailers, and probes. Marketing is conducted through a website catalog, instructional videos, application-specific selection guides, and a newsletter subscription funnel, all targeted at fluid sampling professionals and maintenance engineers.

Checkfluid employs 11–50 people at its London, Ontario headquarters and has no disclosed funding rounds, M&A activity, partnerships, or management changes in the source material, indicating an independent, likely founder-led operating posture sustained over more than two decades.
