What are VCR fittings?
What are VCR fittings?
Swagelok® VCR fittings offer the high purity of a metal- to-metal seal, providing leak-tight service from vacuum to positive pressure . The seal on a VCR assembly is made when the gasket is compressed by two beads during the engagement of a male nut or body hex and a female nut .
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.
What does OD compression mean?
outside diameter
Compression ends are made for a tube which has a specific outside diameter (OD). For example, a ¼” compression fitting is designed to connect a section of tubing which has an OD of ¼”.
What is a VCR gasket?
VCR® metal gasket face seal fittings offer the high purity of a metal-to-metal seal, providing leak-tight service from vacuum to positive pressure. Fittings. VCR® Metal Gasket Face Seal Fittings.
When would you use a VCR fitting?
Swagelok VCR metal gasket fittings are the preferred fittings in the semiconductor industry for high-purity gas delivery systems. They are used when the demand for fast, easy and reliable maintenance is needed on components in a welded system. When a failure occurs in a welded system repairs can be costly.
What is face seal fitting?
Face Seal Fittings (ORFS) They are intended for general applications including hydraulics and vacuum systems. They also have been specified in numerous alternative fuel applications for connecting compressed gas lines.
Can you reuse Swagelok fittings?
If you have made changes in the system design, by moving a fitting to a new location or changing the tubing, you can’t re-use the nuts and ferrules, but you can still re-use the fitting bodies.
Can NPT and NPS be used together?
Sharply angled threads are very critical to joint being tight with no leaks. Thread sealant or tape is typically required to complete the seal. Straight Pipe Threads need a gasket or O-ring to create a seal. While NPT and NPS threads will engage, they do not seal properly with each other.
What is a VCR valve?
VCR means vacuum coupling radiation, providing leak-tight service from vacuum to positive pressure. The VCO line uses an O-ring to form a seal.
How are Orfs fittings measured?
The male fittings have the O-ring in a groove in the flat face. MALE: The measurements for the male are taken from the outside of the threads. FEMALE: For Female fittings, the measurement is taken from the inside of the threads.
