Bulletin 135: Nozzle Accessories

In presenting all 33 colors and the 9 particle photographs on one 8.5×11” chart, our model SGTP-3940 provides convenience that has never before been achieved. Particle assessment is a requirement in section 2-17 of ATA-103, along with color rating. Particle rating is also specified in Section FO-6 of the United Airlines “Fuel Operations Manual.”

The color rating presenting is unique in that oblong windows of adjacent colors are provided so that the technician can more easily compare shades and colors. The filter membrane is placed under the chart, allowing the operator to see four different colors at one time for comparison.

The official ASTM color rating booklet, model GTP-1074-1, which we also produce, was designed so that it could be kept closed to protect the colors from soiling and contamination. This new chart is not provided with such a means of protection so it must be kept in a notebook. Standard 3-ring punchings are provided. For more information on the color rating book, see Bulletin 80.

Made entirely of stainless steel, these couplers are fully interchangeable with Flight Refueling models, as well as those available from A. Searle & Co.. Because we make the caps of aluminum, there is no possibility of thread galling as in other brands when the coupler is also aluminum. We used the Gammon tapered gland O-ring seal principle that has proven to be astonishingly reliable for the last 50 years in the Jet Test QD®.

In addition to the two basic models, we also offer each one with either BSP or NPT threads for installation on fueling nozzles. Refer to the chart below.

Jet fuel particulate contamination testing is performed to ASTM D2276 and IP-216. Conventional equipment on the market is not suitable for high pressures. This is because the plastic monitor is only rated for 100 psi. We have found a way to design a housing which allows testing using standard plastic monitors at up to 450 psi.

For replacement membranes and backup pads, see Bulletin 73.

For testing at pressures below 100 psi, see Bulletin 8.

The three-lug adapter is manufactured in accordance with MS-24484-2 and will accept any aircraft refueling nozzle made by Whittaker, Carter, Zenith, or Avery Hardoll. It will also receive 2 1/2” bottom loading couplers made by these firms but it is not available to accept the product selection feature. It will also receive any U.S. military refueling nozzle that is manufactured to MIL-N-5877.

The connection has a 3” NPT female thread and is made of type 6061 aluminum with an anodized finish.

A plastic dust cap is included. For the optional pressure sealing cap, add “-SC” to the part number.

Fuel sample containers for shipment by air are controlled by UN/ICAO rules. The fuels that are the subject of this bulletin are called Class 3 – Flammable Liquids. The table that follows defines the way various fuels are classified.

We offer a packaging system that conforms to packaging instructions 353 or 355 in 1 or 5 liter drums. These are additional references. Our drums and cartons conform to these requirements:

YOU CAN SHIP VIA CARGO AIRCRAFT ANYTHING THAT IS PERMITTED ON PASSENGER AIRCRAFT.

After the fuel sample has been placed in the drum, tighten the threaded plug. Make sure the fuel resistant gasket is in place. The inner container must never be filled completely so as to avoid leakage or rupture as a result of thermal expansion and/or pressure caused by a temperature build-up.

Turn the drum upside down to be sure of no leakage from the plug.

If lock-wiring is required, secure the threaded plug so that it cannot loosen during shipment. Twist the wire so that force is applied to tighten the plug. Not loosen it.

1 LITER: Place the drum in the carton so it is supported by the corrugated spacer and fill the entire void under, around, and on top of the drum with vermiculite or sawdust to act as an absorbent.

5 LITER: Place the drum in the corrugated carton. It is not necessary to fill the remaining space with sawdust or vermiculite because the combination of the 5 liter drum and corrugated carton has been granted a UN approval. The drum itself is rated 1A1.

Tape all carton edges – top, bottom, and sides – with good quality packaging tape.

Hose dollies, long recognized as more economical and reliable than hose reels for hydrant hoses, are usually fabricated locally from available materials. Professionally designed, our hose dolly overcomes the numerous problems that have occurred with other designs.

Of particular importance in our design is the caster. Look at these features:

• Nickel-plated steel construction
• Ball bearing swivels have stainless steel balls
• Lubricatable bearing design
• Ball bearing wheels
• Durable neoprene tires

All Bacon Bomb Samplers are substantially made of brass and bronze, and heavily nickel plated. Each sampler has but one moving part, no springs, nothing to get lost or out of order, and they are easily cleaned. All models show the same simplicity of design and rugged construction, and also incorporate various desirable features suggested by years of hard usage. All models conform to ASTM specifications D-4057. All Bacon Bomb Samplers are anti-magnetic.

You may coat samplers with protective varnish when used with liquids that will attack nickel and bronze.

This sampler takes truly average samples. When lowered into a tank, liquid flows into the lower end of the sampler only as quickly as air is displaced through the opening at the top. A rugged needle valve permits exact control of the rate of flow. If the sampler is lowered from the top to the bottom of a liquid at a uniform rate and is not quite full when withdrawn, the liquid trapped in the sampler must be a truly average sample.

A plunger keeps the sampler closed until it strikes the bottom of the tank, then the sampler fills. When raised, the plunger automatically falls back into position, closes the sampler, and prevents any contamination by liquid taken at a higher level. This device picks up sediment or water directly off the bottom of the tank.

But a sample can be taken at any point above the bottom by attaching a cable to the top of the plunger, raising it at will to fill the sampler and lowering it to close the sampler. However, average sampling operations cannot be performed with the perfect control possible with the average model.

Extension rods are available to allow a sample to be taken 1” to 12” from the bottom. Order extension kit Model TL-3577.

With a one-gallon capacity, our model GTP-9090 is welcomed by technicians because they no longer must collect repeated samples to obtain enough liquid for the laboratory tests.

If lowered to the bottom of a tank, the sample will be collected at a level 14.2 in (368 mm) above the bottom for model GTP-9090 and 10.8 in (275 mm) above the bottom for model GTP-9021. These samplers are not designed to sample the very bottom of the tank. To meet that requirement, we recommend a Bacon Bomb as described on the front of this bulletin.

Safety from an Electrostatic Standpoint

Yes, our GTP-9021 sampler comes with a 65-foot (19.8m) long stainless steel chain so that the sampler can be grounded to the tank. The greatest danger on tank operations occurs when an “unbonded charge collector” is inserted. If a sampler or any other object enters the tank, there exists a real danger of sparking. Our instruction is that the heavy-duty clamp be attached first to a metal component of the tank, being careful to remove paint or rust that may prevent continuity. The sampler may then be lowered safely into the tank. Rope or cord must never be used.

The unique model GTP-9021 was developed specifically to fit through the small gauging found on U.S. Air Force bases where level gauging electric cables are also present. It was important that there be no tangling of our sampler with those cables and that those cables not be damaged. Therefore, the outside diameter is only 3.1 in (79 mm).
