Yateks Oil Analysis Sampling Pump — 38mm-neck Galvanized, 3/16–5/16" Tubing, Accurate Lab Samples

Yateks Oil Analysis Sampling Pump is a manual extractor engineered to draw clean, uncontaminated engine and machinery oil samples into standard 38mm-neck bottles for reliable lab testing.

Designed for technicians, fleet managers, and maintenance teams, this compact pump streamlines oil sampling from engines, gearboxes, turbines, hydraulic circuits and other oil-filled equipment. Its compatibility with common tubing sizes (3/16"–5/16") and standard sample bottles makes it a straightforward upgrade from improvised suction methods, reducing contamination risk and speeding up routine analysis cycles.

How does the Yateks sampler ensure sample accuracy?

The pump minimizes contact between the sample and external contaminants by mating perfectly with standard oil analysis bottles and tubing. A tight O-ring seal and correct tubing size stop backflow and air infiltration, so what reaches the bottle is representative of the in-service oil.

• Tight 38mm bottle neck compatibility prevents leaks and spills.
• Designed for 3/16"–5/16" tubing to maintain steady suction.
• Galvanized, corrosion-resistant surfaces avoid rust flakes entering samples.

Can I use this pump with different engine oil viscosities?

Yes — the sampler handles a wide range of common oil grades, including 5W-40, 10W-40 and heavier 80W-140 lubricants. Its pumping action and tubing selection provide reliable flow across light to heavy oils without altering the sample composition.

• Works with multi-viscosity oils and heavier gear oils.
• Stable suction across normal temperature ranges for field sampling.
• Prevents oil adherence to the pump body, reducing cross-contamination.

What makes this pump durable for workshop and field use?

The unit is manufactured from materials chosen for oil and water resistance, then finished with a galvanized, rustproof coating. That corrosion protection plus solid seals gives long service life even when used across many machines and environments.

• Galvanized surface resists erosion and oil exposure.
• Robust O-ring and connectors preserve suction integrity.
• Built to endure repeated sampling without performance loss.

How simple is it to operate and maintain?

Operation is intentionally straightforward: attach the correct tubing, seat the bottle on the 38mm neck, and operate the pump. Routine checks of the O-ring and tubing condition are all that's needed to keep the unit functioning reliably.

• Quick setup with standard sampling bottles and tubing sizes.
• Minimal maintenance — inspect and replace O-ring as needed.
• Speeds sampling procedure compared to improvised methods.

Who is this for? Maintenance crews, lube technicians, fleet operators and condition-monitoring teams who need consistent, laboratory-grade oil samples will benefit most from the Yateks Oil Analysis Sampling Pump. It’s ideal for anyone performing routine predictive maintenance or troubleshooting across engines, transmissions, gearboxes, turbines, hydraulic systems and other oil-filled machinery. If you require clean, representative samples quickly and with minimal contamination risk, this sampler is a practical tool to standardize your sampling process and reduce false readings from dirty or cross-contaminated samples.
