Fluid Compatibility Guide - GO Fill
Resource Guide
Which equipment materials are safe for which fluids? Use this guide to confirm pump, hose, seal, and fitting compatibility before purchasing.
Critical safety warning: Using incompatible equipment with certain fluids can cause equipment failure, fluid contamination, fire, or explosion. Always verify material compatibility before using any equipment with a new fluid type. When in doubt, contact our team.
Compatibility by Fluid Type
Use this text to share information about your brand with your customers. Describe a product, share announcements, or welcome customers to your store.
Compatible materials: Mild steel, stainless steel, aluminium, brass, nitrile (NBR) seals, Viton seals, standard fuel-rated hose.
Pump types: Standard vane pumps (12V/24V/240V), piston pumps, hand pumps. ATEX not required.
Filtration: Standard particulate and water-separation filters.
Notes: Diesel is classified as a C1 combustible liquid under AS1940 (flash point >61°C). Standard non-EX-rated equipment is suitable for most diesel applications.
Compatible materials: Stainless steel, aluminium, Viton seals. Avoid standard nitrile in some grades.
Pump types: ATEX/IECEx rated ONLY. Standard diesel pumps are NOT safe for petrol.
Filtration: Must be rated for flammable liquids.
Notes: Petrol vapour is flammable at room temperature. Every electrical component in the circuit must be intrinsically safe or explosion-proof. Using diesel equipment for petrol risks fire or explosion. Tanks require flame arrestor venting.
Compatible materials: Stainless steel (316), HDPE, polypropylene, EPDM seals. NOT compatible: Brass, copper, mild steel, zinc, aluminium, nitrile.
Pump types: Dedicated AdBlue pumps with stainless/HDPE wetted parts only.
Filtration: Stainless steel filter housings only.
Notes: AdBlue corrodes most common metals and contaminates on contact. Contaminated AdBlue damages SCR catalyst systems ($5,000–$15,000 per vehicle repair). NEVER reuse any equipment that has contacted diesel, oil, or other fluids.
Compatible materials: Mild steel, stainless steel, nitrile (NBR) seals, Viton seals, oil-rated hose.
Pump types: Pneumatic piston pumps (3:1 to 5:1 ratio). Compressed air required (6–8 bar).
Filtration: Oil-compatible filter elements and housings.
Notes: Each oil type should have its own dedicated circuit to prevent cross-contamination. Colour-code hoses and dispensing points. Oil requires higher-pressure hose than diesel (rated for pump output pressure).
Compatible materials: Mild steel, stainless steel, high-pressure seals.
Pump types: 50:1 ratio pneumatic piston pumps. Standard oil pumps CANNOT generate sufficient pressure.
Hose: High-pressure grease hose rated to 400+ bar. Standard oil hose will FAIL under grease pressure.
Notes: Grease operates at significantly higher pressures than oil. All hose, reels, fittings, and dispensing guns must be grease-pressure rated. Never substitute oil-rated components for grease.
Compatible materials: Stainless steel, aluminium, Viton seals. Verify all materials against aviation fuel compatibility data.
Pump types: Must be aviation fuel compatible. ATEX rated for Avgas.
Filtration: 4µm minimum particulate, mandatory water separation. Coalescer/separator recommended.
Notes: Aviation fuel contamination can cause engine failure. The highest contamination control standards apply. All wetted components must be verified compatible. Not all diesel-rated equipment is suitable.
Not sure about compatibility? Contact our team with your fluid type and we’ll confirm which equipment is safe to use. It’s always better to ask than to guess — especially with AdBlue, petrol, and aviation fuel where the wrong materials can cause expensive damage or safety hazards.
