Oilybits provide a wide range of fueling and fuel-quality test equipment for the Aviation sector, this section serves as a basic guide to the ranges of products we offer, if you have specific requirements for equipment you are unable to locate on our website, then please do contact us for further information.

Microbial Indicators (Bacteria / Fungus / Yeast Etc)

There are a number of different types of micro-organisms that can grow in certain types of fuel. The biggest problem is presented by a lamentous fungus called Hormoconis Resinae (H Res). Previously called Cladosporium Resinae, and more commonly referred to as “Jet Fuel Fungus”.

For instant results, the FUELSTAT® Resinae PLUS Tests measure the amount of different types of contamination: H Res, bacteria and fungi actively growing in the sample and reports that as the weight of material in the sample. This is a newer, more accurate measurement system than the old Colony Forming Unit (CFU) count, which would take up to 72 hours to grow a representative culture.


Alternatively, still popular for applications where the 72 hour colony-forming process is acceptable, the time served Microbmonitor2 is a cost effective alternative.

Aviation Fuel Analysis Kits

Oilybits offer a range of Aviation Fuel Test Kits, including kits by Gammon Technical Products, and Merck Millipore.


37mm Membranes for Test Monitors in Aviation Fuel Analysis Kits

Oilybits offer 37mm Single and Matched Weight membranes for the above sampling kits, the 37mm membranes are fully interchangeable between Gammon and Merck products.

Water Separation Characteristics

Oilybits offer the Emcee Electronics U.S.A. range of test equipment, including the Emcee Electronics, Model 1140 Micro-Separometer Mark X, and Emcee Electronics, Test Expendables Including Coalescer Cells, 6-Pack

Electrostatic Conductivity

Oilybits offer the Emcee 1152 & 1153 Digital Conductivity Meters to ASTM D2624 for the testing of Aviation & Distillate Fuels.

Suspended / Miscible Water Detection

The Shell Water Detector is manufactured following strict quality assurance standards in a purpose-built, humidity-controlled facility. For over 50 years, operators across the world have relied on the Shell Water Detector to check their aviation fuel for suspended water that cannot be detected by visual inspections. The detector capsules are widely used, thanks to their effectiveness and simplicity.

Kolor Kut Modified Water Finding Paste has been designed for use in Methanol / Ethanol enriched fuel systems. Alcohols are soluble in fuels in all proportions when they are water-free (Anhydrous) but relatively small amounts of water can cause separation of alcohol from the fuel. The mixture settling to the bottom of the storage tank contains a high concentration of alcohol and cannot be detected be most water detection pastes. Phase separation alcohol solutions with as little as 6% water will cause a positive reaction to the paste.

Free Water Detection

Oilybits offer a range of Gauging Pastes for the identificartion of free water in bulk fuel storage tanks, some of the pastes we offer are:

A special "Water Finding Rule" is also available, for use with the pastes.

Bulk Fuel Storage Tank Sampling

Oilybits offer a range of Sampling Gauges for the sampling of bulk fuel storage tanks, our full range of samplers can be found here: Sampling Gauges

For Aviation use we always recommend the use of ATEX approved samplers, and so the range is limited to the following products in conjunction with an ATEX Approved Hand-Winch for the lowering and retrieval of the sampler:


Bulk Fuel Storage Tank Dipping

Oilybits offer the Richter brand of tank dipping tapes, the purpose of dipping tapes is to categorically confirm the depth in the tank where an electronic gauge may not be trusted to perform the duty, at the same time as the depth is measured the fuel may also be sampled. The full range of Richter tapes can be found here: Richter Dipping Tapes

There are two fundamentally different products on offer, non-IPM (Institute of Petroleum Measurement) tapes of light and heavy duty, and IPM tapes in heavy duty, with or without certification. Oilybits recommend the use of IPM tapes in Stainless Steel for Aviation applications:

Oil Level Gauging Pastes

In conjuction with a dipping tape, the user may use a proprietary oil level gauging paste to aid visual identification of the oil level. Oilybits supply a range of Oil Level Gauging Pastes;

Hydrometers and Hydrometer Tubes / Measuring Cylinders

Oilybits offer a standard range of Hydrometers suitable for checking the S.G. of Avgas & Jet-A1, we can also offer customised Hydrometers where special characteristics are required.


Fuel Sample Handling

Two simple products are offered for the purpose of fuel sampling, a Grounded Bucket, and a Grounded Funnel. The bucket may be used for transporting contaminated sampling equipment, and the funnel may be used for transferring fuel samples into bottles for laboratory analysis.

About Our Unique Grounding Cables...

  • Manufactured by Oilybits in our U.K. production facility.
  • Polyolefin yellow/green stripe, heat shrink cable sheath - the correct colour for earthing applications and fully resistant to Oils, unlike PVC.
  • 6mm2 tinned copper, braided cable for greater resistance to acidic / oxidised oils.
  • 1m length of cable.
  • Cable end terminals are fused with solder to prevent fraying, loosening, and contamination / corrosion of the cable, thereby ensuring a stable ground connection.
  • RACO, cast brass, 70mm grounding clip, with red handles.
  • 304 stainless steel nuts and bolts throughout, featuring Nyloc Nuts or Shake-proof Washers to prevent loosening, thereby ensuring a stable ground connection.
  • Nylon inner seal on vessel bolt, to prevent leakage of contents above the terminal. Oil resistant.
  • A superior product to that of our competition.

Grounding Reels

Oilybits offer our Static Grounding Reel, Stainless Steel, ATEX Approved.
