GENERAL
Q: Does Western sell direct?
A: No, Western products can be purchased through our wholesalers and distributors. Western will also sell direct to original equipment manufacturers.
Q:
How can I find a distributor of Western Products?
A: You can find your nearest distributor by going to www.gawda.org. The front page displays a distributor search tool. Enter your zip code and your travel radius in miles and your nearest distributors will be displayed.
Q:
What are CGA numbers?
A: Compressed Gas Association (CGA) numbers are an identification system for inlet and outlet connections used on various products.
Q: What is a BAR?
A: BAR is the British unit of pressure measurement similar to PSIG (Pounds per Square Inch Gauge). See pages 6 and 7 of our Industrial Equipment Catalog for a conversion chart.
1 BAR = 14.5 psig
Q:
What is a kPa (Kilopascals)?
A: Kilopascals are the metric unit of pressure measurement similar to PSIG. See pages 6 and 7 of our Industrial Equipment Catalog for a conversion chart.
1kPa = .145 psig
FITTINGS
Q: Can I order a washer for CGA 240?
A: No, it is not available. The latest version of CGA V-1 (Standard for Compressed Gas Cylinder Valve Outlet and Inlet Connections) which defines the CGA 240 connection requirements does not require it.
Q: Do you have a plug for a CGA 580?
A: We have a male plug, but do not have a female cap. An adapter will be needed in order to cap a male CGA 580 connection.
See page 24 and 45 of our Industrial Equipment Catalog for a listing of available pressure tight caps & plugs.
FLASHBACK ARRESTORS
Q: Can flashback arrestors be used with hydrogen?
A: Only in low pressure applications (up to 22 psi) in the FA-10 and FA-30 arrestors.
Hydrogen cannot be used with the FA-2 and FA-3 style arrestors due to pressure limitations of the devices.
Q: How do I know when a flashback occurs?
A: A popping noise can usually be heard when a flashback occurs. Due to ambient noise levels, it may not be possible to hear when a flashback has occurred, so this method of determining whether a flashback has occurred should not be relied upon. The instructions provided with the flash arrestors inform the user about how to determine if the flashback arrestors are still suitable for service.
Q: How long will a flashback arrestor last?
A: This is variable and dependent on the number and intensity of the flashbacks. There is a carbon build up after each flashback and arrestors cannot be cleaned or refilled. They must be replaced if the pressure drop through the arrestor exceeds the values listed in the instructions.
Q: What is the significance of the green and red bands on the arrestors?
A: The color bands identify the gas service of the flash arrestor – oxygen (green), fuel gas (red).
HOSES
Q: What size ferrule should I order?
A: The size of the ferrule you purchase is typically selected based on the outside diameter of the hose (see page 20 & 21 of the Industrial Equipment Catalog). It should also be noted that making a proper connection is dependent on several factors including hose type (light duty, heavy duty, etc.), hose grade (e.g. grade T), hose material, hose outside diameter, hose inside diameter, barb style (straight, spiral, etc), barb outside diameter and length. Since a good connection is dependent on so many variables, it is important to leak test assemblies prior to putting them into service.
HOTSPOTTERS
Q: Can the Hotspotter be used with propylene?
A: No. Western has not tested the Hotspotter with this gas so we can not recommend its use.
Q: What is the flame temperature?
A: 2300 degrees F.
Q: How long will a tank last using a weedburner?
A: A 20 pound tank will last 45 minutes at the full flow setting.
Q: Can I purchase replacement hoses for the Hotspotters?
A: Yes. For model WB-100, the replacement hose assembly part number is WB-100-27. For models WB-101 and WB-102, the replacement hose assembly number is WB-100-25.
Q: Can I replace the fittings on the hose?
A: No, Western recommends replacing the entire hose to ensure required integrity is maintained.
Q: Can I replacement shut-off valve?
A: No, Western recommends replacing the entire handle assembly to ensure required integrity is maintained.
Q: What kind of material is the hose?
A: Neoprene.
Q: Can you get the hose in a longer length?
A: No, the hose length has been designed to maximize the function and safety of the Hotspotter. Western does not recommend using a longer (or shorter) hose length.
REGULATORS
Q: Do you have a regulator for propylene?
A: No.
Q:
What size are the threads on the RWB-3-8 outlet orifice fitting?
A: ¼ NPT Male inlet X CGA 022 (9/16-18 UNF-2A) outlet
Q: What size are the threads on the AW-432B outlet connection?

A: AW-432B
Q: What is the orifice size in the flow gauge regulators?
A: Æ.036, part number 32-64F.
Q: What is the outlet pressure of the REF series flowmeter?
A: The regulator reduces the cylinder pressure to 50 psig, which feeds the flowmeter. The pressure downstream of the flowmeter will drop to around 5 psig when flowing. When there is no flow, the pressure at the outlet of the flowmeter will build back up to 50 psig.
Q: Can you turn the flowmeter horizontally?
A: No, it must be vertical.
Q: What is the outlet fitting on the RFS series?
A: AW-432B
Q: What is the outlet pressure of the RFS series flowmeter regulator?
A: The regulator reduces the cylinder pressure to 50 psig, which feeds the flowmeter. The pressure downstream of the flowmeter will drop to around 5 psig when flowing. When there is no flow, the pressure at the outlet of the flowmeter will build back up to 50 psig.
Q: What size are the ports on the body on the RWS flowmeter series?
A: Inlet port: 1/8 NPT female
Outlet port: 9/16-18 RH male and 5/8-18 RH female
Q: What is the typical cylinder inlet pressure provided to a preset CO2 regulators (e.g. RP320’s)?
A: The typical carbon dioxide cylinder pressure is 850 psig (at 70 °F).
It should be noted that the carbon dioxide cylinder pressure will vary depending on ambient temperature. The pressure will drop to about 300 psig at 0° F. and will increase to about 2000 psig at 120° F. ambient temperature.
Q: What is the delivery pressure of the FROG (Flow Regulator Orifice Gauge)?
A: 30-60 psig

Q: Can I use the argon FROG with air?
A: No, the device has been constructed with gas specific fittings, which do not allow connection to air cylinders.

Q: What is the low range operating temp of the RHP series?
A: 0 degrees F.
Q: Can I get a repair kit for my RHP regulator?
A: If the regulator was made prior to 1999, no repair kit or replacement parts are available and the regulator should be replaced. If the regulator is newer than 1999, contact our customer service department to place your order for a repair kit.
