Reliable Samples Begin with the Right Equipment
Your oil test samples are only as good as the tools you use.
The right oil sampling hardware ensures you’ll get an accurate oil sample that represents the true condition of your equipment.
Fluid Life offers a complete range of sampling tools and collection devices that make sample taking easy and effective. Contact our Order Desk toll free at 877-962-2400 or purchase online.
When taking oil samples, you want to ensure you are taking the samples safely and accurately.
Selecting the right sample fittings for your unique situation can help.
From a safety perspective, utilizing a sample valve can keep your personnel and equipment safe in several ways:
- Sample valves allow oil to be directed safely and cleanly to the sample bottle, avoiding burns if trying to reach for a drain port.
- You can also install remote access options so you can ensure sampling is done away from any equipment hazards.
- Contamination is reduced significantly as sample valves allow you to take a sample from a closed system.
- You can avoid downtime by sampling while equipment is running.
Accuracy is also key for a successful oil analysis program. If using drain valve or drop tube sampling, you may not be getting reliable results. For example, if taking samples from the oil drain, you may see elevated wear metals, contamination, or water in your oil sample results due to settling. Plus, because these methods require sampling to occur when the machine is shut down, you may not get an “in-operation” representative sample.
Sample valves let you take samples safely from the active zone while equipment is running, giving you reliable samples without needing to shut down your equipment or introducing contamination.
Sample Valves & Accessories
Pressurized Systems
Engines, transmissions, compressors and hydraulics
- Sample valves should be installed downstream of components to be monitored, but before the filter
- Valves for pressurized applications include: Pushbutton (KP), B-Series and KST-Series (with probe)

B-Series Sample Valve
Euro-Probe style sampling valve designed for high pressure low viscosity oil sampling.

KP-Series Sample Valve
Pushbutton valve for pressurized oil and coolant system applications.

KST-Series Sample Valve
Uses a 2mm probe that is compatible with SOS, Probalizer, and Quick Draw valves.
Low / Non-Pressurized Systems
Splash-lubricating gearboxes, reservoirs
- A drain port can be used by inserting a sampling valve with attached pitot tube that’s positioned away from the sludge at the bottom
- A breather port is also an option for pitot tube installation
- Valves for low or non-pressurized applications: M-Series, L-Series

38U Sample Pump
Comes complete with a 38mm suction pump, heat resistant tubing and a flush jars.

L-Series Sample Valve
Low or no pressure, high viscosity sampling (splash lubricated equipment / reservoirs).

M-Series Sample Valve
Popular Euro-Probe style sampling valve with metric 16×2 probe thread.
Additional Sampling Hardware

QR Information Tags
Metal tag for spot identification of oil sampling points or component task locations.

Grease Sampling Kit
Kit includes two options for grease sampling with slitted coring tube or coring spatula.
Sampling Procedures
The key to a successful oil analysis program is to first establish the ‘normal’ baseline for a given asset. Every asset may have its own unique conditions for maintenance and operations, and determining its typical levels of contamination and wear help identify when those levels become abnormal.
Consistent sampling at regular intervals, utilizing a repeatable procedure, will reduce the noise within the data to make it easier to spot any deviations from normal results, providing the earliest, and proper, notification of necessary action.
