Can compression fittings hold vacuum?
For fusor vacuum conditions, you definitely can get away with compression fittings, but if you want to use your chamber and fittings for other experiments that need ultra high vacuum go with VCR.
What does VCR fitting stand for?
VCR means vacuum coupling radiation, providing leak-tight service from vacuum to positive pressure.
How much pressure can Swagelok fittings hold?
Features: Temperatures from 70 to 400°F (20 to 204°C); Working pressures up to 275 psig (18.9 bar); Sizes from 1/8 to 1/2 in.
What are vacuum fittings?
Vacuum fittings are flanged vacuum components comprised of a fixed flange on one end of a tube, or a fixed flange on one end and a rotatable flange (on CF flanged assemblies) on the other end of a tube. This rotatable vacuum flange eliminates bolt-hole alignment issues with mating fittings or flanges.
Can air hose be used for vacuum?
Large air hose with wire reinforcement or hydraulic hose can work great for this. Clear wire-reinforced PVC hose is good for this and reasonably inexpensive.
What is a VCO fitting?
VCO® O-Ring Face Seal Fittings are engineered for rapid assembly in pipe, tube, and welded systems for general industry, high-pressure, high-purity, and critical vacuum applications. Sealing is accomplished with a captive O-ring in the fitting body, available in a variety of materials.
Are Parker and Swagelok fittings interchangeable?
Is Parker CPI™ Really Interchangeable? Yes. All threads, the seal seat angles and position, tube insertion depth, hex sizes and width, etc., are the same as Swagelok®. The fitting is totally the same as Swagelok® in all functional dimensions of the body and nut.
What is VCO fitting?
What determines the pressure rating of a compression Swagelok connection?
The pressure rating of a Swagelok tube fitting depends on the lowest rated component in the system in which it is installed. Sometimes the lowest pressure rated component is a pipe thread, a pressure gauge, or a valve.
How much pressure can an fittings hold?
Industrial stainless-steel fittings are often rated to 10,000 psi. Specially designed stainless steel fittings can have pressure ratings as high as 20,000 psi. Typically, stainless steel fittings are more expensive than those made from other materials.
What is vacuum bagging process?
Vacuum bagging (or vacuum bag laminating) is a clamping method that uses atmospheric pressure to hold the epoxy-coated components of a laminate in place until the epoxy cures.
What is KF flanges?
KF flanges are ISO-standardized vacuum fittings that provide a vacuum seal by compressing a rubber O-ring between two mating surfaces. Also referred to as NW, QF, or DN flanges, KF flanges are ideal for quickly assembling vacuum systems thanks to their ease of use, maintenance, and reusability.
