What is a DISS fitting?
Diameter Index Safety System, a way to ensure that one type of gas fitting will only connect to appropriate hoses, tubing and devices.
Makeup gas compressor spill back valve function?
It is a quick response valve, which opens fully in 1.5-2 seconds. basically will be of fail open type. Its opening depends on the surge control.
What is the maximum gpm through half inch copper pipe at 25 psi?
When you say 1/2" are you talking about 5/8 OD or nominal size and which type of copper? K /L/ M as there is friction looses to consider I am referring to 1/2" nominal type L copper pipe, and the friction loss is negligent because the section of 1/2 inch tubing is only 2" nipples on either side of a electric shut off valve. The actual set-up is 1" PVC supply at 65psi, reduction fitting to 3/4" into a pressure redusing valve, 3/4" out of the valve through another reduction fitting to 1/2" into and through the shut-off valve, then into the furnace. Distance from the first 1' to 3/4" reducer to the furnace is only a distance of about 14". Hope this helps.
What is the difference between a globe valve and a ball valve?
The Globe valves are generally used to control the flow rate and ball valve used for open /close purpose only.A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it.
Which valve is prefered to use for ammonia tanks a globe valve or a gate valve?
If the purpose of the valve is to modulate flow, a globe valve is preferable. If the valve is only on-off, a gate valve is preferable because of lower pressure drop when the valve is open. As wikipedia , A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. So i think it is a globe valve to use in steam pipeline.
What type of fitting do you use to connect PVC pipe to unthreaded galvanized pipe?
You can't. There is no fitting to do this. Galvanized has to be threaded.
Where is the fuel filter located on a 1996 Chevy Cavalier?
Follow the fuel line from the engine toward the rear of the car and you will find it. the fuel filter is located under the vehicle between the fuel tank and the EVAP canister. the inlet fitting is a conventional tube nut on the end of the inlet line the outlet fitting is a quick connect type fitting.
How do you define the coefficient of incipient cavitation?
The cavitaion index across a valve or pipe fitting is defined as the ratio of difference between upstream pressure and vapor pressure to the pressure drop across the valve or fitting. The index at which incipient cavitation, damage, or choked flow occurs is based on testing and depends on the type of valve or fitting.

Diameter Index Safety System, a way to ensure that one type of gas fitting will only connect to appropriate hoses, tubing and devices.
Where do you add freon to your 2001 Ford Focus?
R 134A freon is added into the "quick connect type" fiiting, located on top of the AC accumulator, which is located underneath the front of the passenger side fenderwell. First, raise the car with your jack placed behind the front tire. Then remove three screws that secure the black plastic fenderwell cover. One screw has a torx head and is located at the front lower edge of the fender. The other two are Phillips head plastic screws located in front of the strut. With the three cover screws removed, pull down the front portion of the fenderwell cover. This will expose the AC accumulator, which looks like a quart sized aluminun can. Now, unscrew the valve cover from the quick connect fitting and connect your AC recharging hose to the fitting. By the way, it pushes on and snaps onto the fitting. Now, follow the instructions that came with your AC recharge kit, for the dtermining the corrct amount of freon to add. Finally, replace the fitting valve cover, the fenderwell cover/screws and your done.
What is a sweat inlet?
It is probably referring to the type of fitting. A fitting that is soldered to a copper pipe. It is called sweating when you use solder and a torch to connect copper pipe together or attach fittings to copper pipe.
Were do you add freon on a 2003 ford expedition xlt?
LOCATE THE SERVICE FITTINGS Next, you need to locate the service fittings on the A/C system. There are two: a LOW side fitting and a HIGH side fitting. The LOW side fitting is usually located on the suction hose or line that goes from the accumulator to the compressor. The HIGH side fitting is located on the line that goes from the compressor to the condenser. R12 Low Side 7/16 in. threaded ß----------à R134 Low Side 13mm Quick-disconnect R12 High Side 3/8 in. threaded ß----------à R134A High Side 16mm Quick-disconnect On older R12 systems, the LOW and HIGH pressure service fittings are screw-type Schrader valves. On newer R134a systems, the LOW and HIGH side service fittings are quick-connect style fittings. The LOW pressure fitting is SMALLER than the HIGH pressure fitting.
Can you tell if a car has been converted to use R-134a freon?
There are two ways. The old R-12 A/C's have a "screw thread" style service fitting for adding refrigerant. These resemble a tire valve. R-134A systems use a "quick connect" type fitting with no external threads. These fittings are on stock R-134A and R-12 systems that have been retrofitted to R-134A. The purpose is to prevent someone from charging R-12 into an R-134A system and vice-versa. Also, retrofitted A/C's should have a label saying "Retrofitted to R-134A," or something to that effect. The label should also say the freon charge weight and type of oil in the system, usually a polyol ester oil (POE or ester) in retrofitted systems and a polyalkylene glycol (PAG) in stock R-134A systems. Look for both the "quick-connect" style fittings and retrofit labels on the vehicle in question.
Where is the schrader valve on a 1999 Ford Expedition?
SCHRADER VALVE Definition: A type of valve fitting that opens when depressed. Schrader valves are used in tire valve stems, on air conditioning hoses and on the fuel rails of many fuel injection systems. http://autorepair.about.com/cs/generalinfo/l/bldef_724a.htm
What tool is needed to remove fuel line?
Since I do not know the year or model of the vehicle, I am assuming you are referring to the quick connect type fuel line fittings on most Fords. There are inexpensive removal tools available at most automotive stores. (Give them the make and model of the vehicle as there are different types and sizes of connectors) The tool slides onto the fuel line, by pushing the tool into the fitting it releases the fingers in the fitting. Make sure the fitting is clean and well lubricated as dirt can prevent it's release.
