18/15
ISO code of "new" drum oil — already too dirty for servo valves
New Oil Isn't Clean
Drum oil straight from your supplier arrives at ISO 18/15. Servo valves require 16/14/11. You may already be violating your OEM spec before the machine starts.
×2
The Doubling Rule
Each 1-point increase in your ISO code doubles the particle count. A code of 22/18/13 has 4× the contamination of 20/16/11. Small numbers hide massive differences.
Fabrication is the Source
Cutting, crimping, flaring, and bending introduce contamination before your system sees a drop of oil. Our cleaning systems address the source — not the symptom.

7 Industries Served

YOUR INDUSTRY.
YOUR ISO TARGET.

Generic contamination messaging doesn't convert. Every industry has its own financial pain point — and its own ISO code to hit.

Mining
Dusty, wet, extreme-temp environments. A failed hydraulic cylinder on a haul truck means $40K in parts and $10K/hour in lost production.
Target: 17/15/12
▲ Non-compliance: $10K+/hr downtime
Fluid Power
Post-fabrication contamination is introduced during cutting, crimping, and flaring — before the machine ever starts. Your hose assembly is only as clean as your launcher.
Target: 17/15/12
▲ Customer pump failure = your warranty problem
🏗
OEM Equipment Mfg
You must ship assemblies meeting your customer's ISO cleanliness spec. Failure to comply is a warranty claim you own. Caterpillar, Parker, Bosch Rexroth all publish requirements.
Target: 17/15/12
▲ Non-compliant shipment = voided warranty
🍺
Food & Beverage
Product recovery between runs, residue contamination, and excessive water/chemical use are costing you margin on every batch. Our tube projectiles minimize all three.
Target: Regulatory compliance
▲ Cross-contamination = product recalls
💊
Pharmaceuticals
Strict cleanliness during fabrication, with precise residue removal when switching products. Stainless-compatible tube projectiles perform where chemicals can't.
Target: FDA/GMP compliance
▲ Residue contamination = batch rejection
🥛
Sanitary / Dairy
Liquid and slurry removal from sanitary tubes without water waste. Our projectiles recover what water throws away and eliminate unnecessary chemical CIP cycles.
Target: 3-A Sanitary Standards
▲ Water CIP waste: hundreds of gallons per run
🏗
Construction / Earthmoving
Heavy use, mandatory dealer cleaning during fabrication. Hand-held launchers and clean-seal capsules are the only practical field solution for mobile hose assemblies.
Target: 19/17/14
▲ Contaminated assembly = early pump failure
ISO 4406 Education Hub

WE OWN
THE KNOWLEDGE.

The deepest free ISO 4406 education resource available to maintenance engineers, reliability managers, and hydraulic technicians. Anywhere.

01
Why New Oil Fails Your System
The widespread assumption that fresh drum oil is clean enough for hydraulic systems. It isn't. We show the data, explain why, and tell you exactly what to do about it before your machine starts.
02
Silting: The Invisible Killer
Particles below 10 microns don't show up in visual inspections — but they wedge into valve spool clearances and cause sticktion, erratic response, and premature failure.
03
How to Sample Oil Correctly
Bottle sampling introduces its own contamination. We explain why online particle counting is superior, when bottle sampling is acceptable, and how to avoid the most common mistakes.
04
ISO 4406 Explained: The Full Guide
The three-number code, the logarithmic scale, component cleanliness targets, and how to set your system's target based on its most sensitive component — with the full reference table.

KNOW
YOUR
STANDARD

The spec exists. Most shops don't know it. We do — and we'll show you exactly how to hit it.

01 Foundation

ISO 4406 Explained

What the three-number cleanliness code actually means, how particles are counted, and why 16/14/11 is not the same as 18/16/13 — in plain language.

Read the guide →
02 Application

Component Sensitivity Chart

Servo valves need 16/14/11. Vane pumps tolerate 18/16/13. Your target depends on what you're protecting — not a universal standard.

03 Aerospace

NAS 1638 for Defense & Aerospace

If your customers touch Boeing, defense, or space applications — this is the spec they're working to. Most shops don't even know it exists.

06 Troubleshooting

Why Your Clean Is Failing

Wrong projectile sizing, bad pressure, improper technique, recontamination at the fitting — every failure mode diagnosed with corrective action.

Verification

PROVE
IT.

Anyone can say they cleaned to spec. CleanSpec is the only platform that sells you the tools and methodology to verify it yourself — before your customer does it for you.

ISO compliance without verification is just a claim.
We give you everything to make it a fact.

Select your application target
Use the configurator to identify your ISO cleanliness target based on component sensitivity. Servo valve or cylinder — the target is different. Know yours before you clean.
Clean with the right projectile
Correct projectile size, correct density, correct pressure — all specified for your exact assembly type. CleanSpec tells you before you pull the trigger.
Run a particle count on your own floor
Sample the flushed fluid with a portable particle counter — the CS-VERIFY PRO counts at 4, 6, and 14 micron simultaneously and outputs an ISO 4406 code in seconds. No lab required.
Document and record your verified result
Export a timestamped cleanliness report tied to your assembly record. You own the proof. Your customer receives it. Your ISO code is no longer a claim — it's a number on a page.
