Wansni QYQ01 Oil Sampling Pump for Engine, Transmission & Hydraulic Oil Analysis

A manual oil sampling pump for workshops and field technicians who need to pull fluid samples from engines, transmissions and hydraulic systems for analysis. It draws a sample through a push-pull piston that builds vacuum, so no power source or batteries are needed, which suits outdoor shops and remote job sites. The pump is built to fit standard 38mm neck sampling bottles and works with 3/16 inch tubing. It is intended for a range of oil viscosities, including 5W-40, 10W-40 and 80W-140. Sampling without draining the equipment helps keep samples representative and reduces cross-contamination between machines. It is suitable for engine oil, transmission fluid, hydraulic oil and gear lubricant, and is made from corrosion-resistant materials to handle oil, water and regular abrasion on the job.
