Bulletin 131: Sampling Quick Disconnects

Interchangeable with Flight Refueling Couplers

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.

Bulletin 127: High Pressure Membrane Tester

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.

Bulletin 123: Test Buckets

White Buckets

We now offer high-grade, 2 1/4 gallon, powder-coated white buckets. The coating is specifically formulated for outdoor and fuel use and is more durable than porcelain. They have passed a Gammon six-month sunlight exposure test. These buckets were accepted in an ASTM meeting as equal to white porcelain for color testing.

GTP-1748B

Plastic Buckets

Our plastic containers are made with a conductive (aluminum) electrostatic bonding device to collect static charges so they can be safely carried away, using the bonding cable (included). Note the bonding lug at the top for use in membrane tests. This device also serves as a level indicator. The operator can clearly see the fuel level as it reaches the notches which are at accurately calibrated levels. Plastic buckets are not approved as standard “white buckets.”

GTP-2518-2 0.5, 1.5, and 2 gallons graduated

Bulletin 119: Sample Shipping Containers UN/ICAO

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:

AGENCY INNER CONTAINER (STEEL) OUTER CONTAINER (FIBERBOARD)
UN/ICAO Rated 1A1 Rated 4G
IATA Rated Ic3 Rated T5A

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

How to Order

Model No. Description
TL-3816 1 liter drum
TL-3816-A 1 liter drum with safety wire holes in the plug
TL-3817 1 liter drum with carton
TL-3817-A 1 liter drum with safety wire holes in the plug, and carton
TL-3818 5 liter drum
TL-3819 5 liter drum with carton
TL-8335 One 16 lb. bag of vermiculite (2 lbs. fills the void space in a 1-liter carton)

Weights and Dimensions

1 liter drum in carton 7 x 7 x 12.2 in (178 x 178 x 310 mm) – 2 lbs (0.9 kg)
5 liter drum in carton 8.8 x 8.8 x 8.8 in (225 x 225 x 225 mm) – 4.4 lbs (2 kg)

How to Package

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.

Bulletin 115: Bacon Bomb and Tank Samplers

Bacon Bomb Samplers

Designed by Charles V. Bacon, Chemical Engineer

Makes possible two sampling methods important to every company handling liquids in tanks.

FOR SAMPLING: Jet Fuels, Petroleum Oils, Fish Oils, Solvents, Tar Oils, Sugar, Glycerin, Fruit Juices, Chemical Solutions, Molasses, Varnish, Vinegar, Latex, Vegetable Oils, Laquer, Beverages, Fisheries

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.

Average Sampler

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.

Model Capacity Diameter Height
TL-3576 16 oz. 2 3/4″ 12″

Bottom Sampler

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.

Model Capacity Diameter Height
TL-3572 8 oz. 2 1/4″ 10″
TL-3573 16 oz. 2 3/4″ 12″
TL-3574 32 oz. 3 5/8″ 16″
TL-3575 4 oz. 1 7/8″ 9″

Accessories

GTP-9548-20 Chain assembly with ground clamp for use with Bacon Bombs, 20′

In-Tank Samplers

  • No copper or brass

  • All stainless steel or aluminum

  • Model GTP-9090 (aluminum) has a capacity of 1 U.S. gallon (3,785 ml)

  • Model GTP-9021 (stainless steel) has a capacity of ⅓ U.S. gallon (1,260 ml)

  • Stainless steel chain is tangle resistant, 65 feet (18,300 mm)

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).
