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. … VCO fittings install easily in limited spaces, with no axial clearance required.
What does VCR fitting stand for?
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.
When would you use a VCR fitting?
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. VCR fittings facilitate timely maintenance and leak-tight integrity in a make and break system, and minimize disruption to the facility.
How do you tighten a VCR fitting?
What type of fitting is seal Lok?
O-ring face seal
The Seal-Lok fitting is an O-ring face seal type fitting that consists of a nut, a body, an O-ring and a sleeve (Fig. A1). As shown in Fig. A3, the tube is flanged to 90° (or the tube may be brazed instead to a braze-type sleeve).
How big is Swagelok?
About Swagelok
Swagelok Company is an approximately $2 billion privately held developer of fluid system products, assemblies, and services for the oil and gas, chemical and petrochemical, semiconductor, and transportation industries.
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”. When the nut (which contains the ferrules) is tightened, it compresses the ferrules onto the tubing to make the seal.
How does swagelok seal?
Gas seal. A Swagelok tube fitting forms a gas seal by means of the burnishing that occurs in two places: between the front ferrule and the tube fitting body, and between the front ferrule and the tubing.
How does a metal gasket work?
Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal.
What is the difference between compression and NPT?
NPT or IPT pipe threads are tapered, Compression Fitting Threads are Parallel. … That’s true even when the male or female fitting is comprised of the threaded end of a pipe. On the other hand compression fittings and flare fittings use threads that are cut in parallel, without taper.
What is the difference between MIP and MPT?
MPT stands for Male Pipe Thread and MIP stands for Male Iron Pipe which both indicate a male fitting with NPT threads.
Are NPT and IPS the same thread size?
National Pipe Tapered (NPT) and Iron Pipe Straight (IPS) are two commonly used thread standards in plumbing. … NPT and IPS nominal sizes are always the same.
Is black iron pipe NPT threads?
Steel pipe comes in 21′ threaded pipe joints. The pipe has NPT threads on both ends and a coupling on one end making a full joint mipt x fipt overall. Cut lengths won’t include a coupling; if you need one, you should order one.
Can you use compression fittings on stainless steel?
Compression fittings are most commonly used with hard tubing because the tubing wall must be rigid enough to resist the compression forces applied by the ferrule. Common choices include metallic tubing (such as stainless steel or copper) and stiff plastic tubing (such as PEEK, nylon, Teflon®, Kynar®, or polyethylene).
Can brass fittings be used with stainless steel?
Using brass fittings on stainless steel tubing is not recommended. Brass is softer than steel and may not seal onto the tubing as well, risking leaks. You might also see galvanic corrosion, which is a process where the corrosion is accelerated by 2 dissimilar metals contacting one another.
What is the difference between MNPT and NPT?
NPT stands for National Pipe Thread and is an American standard thread. It may also be reffered to as MPT , MNPT or NPT (M) for male external threads and FPT, FNPT or NPT(F) for female interal threads. … Both threads have the same pitch, angle (60 degrees) and shape (flat peaks and valleys).
What does IPS stand for in plumbing?
Iron Pipe Size
Iron Pipe Size (IPS) is an old pipe sizing system that came was started in the early 19th century. It remained in effect until after WWII and was mainly used in the US and UK. When IPS was introduced, pipes were cast in halves and welded together.
Is MPT and NPT the same?
MPT and FPT are both sub-types of NPT. National Pipe Threads (NPT) have tapered threads.
