Note: On sizes 14" and larger the Outside Diameter becomes the Nominal Size as opposed to the smaller sizes were the Inside Diameter is the Nominal Diameter. 0000225466 00000 n
Using Class 200 pipe saves weight and money but has lower strength. Absorbs vibration and noise from pumps, compressors, engines etc. Even manufacturers specializing in AN-style fittings strictly for motorsports tend to skip over the 5AN size for the most part. Note that we did not list the hex sizes. 0000332313 00000 n

Resistance to moisture, fire, abrasion & penetration. If you are using Flexible PVC pipe, look for the blue box inset in the yellow box for pressure ratings. Keep in mind that you have to begin the measurements from the interior wall of the circle. Hard-line tubing is measured by the outer diameter (OD). Flexible duct sizing relates to more than just the ID sizes of a hose. ** Conventional rubber-lined stainless braided hose, except 3AN which is PTFE-lined. The idea behind AN hoses and AN fittings was to provide a flexible alternative to rigid tubing in plumbing systems on aircraft and military vehicles. Hex sizes are not standardized. 0000148938 00000 n
One glaring mismatch is the popularity of 5/16" (8mm) fuel hose on automobiles.
Moreover, Corrugated Metal Hoses are also said to dampen or absorb the noise and vibrations generated from the pumps, engines, compressors, and other equipment. 0000226545 00000 n

The AN numbers refer to the tubing OD in sixteenths of an inch. The weight of the piping should not be supported by a flexible metal hose assembly. 0000549371 00000 n
AN hose sizes are based on the nominal OD of the tubing with a matching ID. <> 2004 - 2022 Pegasus Auto Racing Supplies, Inc. -, Thread Detective Thread Size Identifier Tool Kits, Pegasus Auto Racing Supplies Plumbing Technical Information, 3/4 NPT (0.95"), 11/8-7 UNC (0.970" - 0.998"), M27x2* (0.978" - 0.993"). As a result, OD measurements tend to be slightly greater than the ID. Good corrosion resistance. HOSE SIZE IS DETERMINED BY ITS INSIDE DIAMETER (A), TUBE IS DETERMINED BY ITS OUTSIDE DIAMETER (B). 0000481566 00000 n

You should also keep in mind to consider the overall length of the hose you want for your application. stream x}i]E_mj_34m2#(q$&eI3vZnniwj9k8Iu-xg?^}.8sr6 xWA`o+qR^ESVFez0!__rN 0000313242 00000 n
But for constructed (structural) projects you can generally mix and match different classifications. Did you notice that for hose part numbers, we talked about inside diameter, and for tube part numbers, we referred to an outside diameter? 0000917991 00000 n

HOSE SIZE IS DETERMINED BY ITS INSIDE DIAMETER, TUBE IS DETERMINED BY ITS OUTSIDE DIAMETER. Tubing is known by OD, but AN hoses are sized according to the tubing ID -- not the hose OD or even the hose ID. 
Hose lengths can vary from one class of flexible ducting to another. Most people think about hoses as being flexible and tubes as being rigid, but in fact, there are some very rigid hoses, and some very flexible tubes. 0000730457 00000 n
Stainless Steel Corrugated Hose assists in economical installation against rigid piping in compact locations. * The thread pitch on these metric sizes are also quite close to the thread pitch of some SAE sizes (1.0mm = 25.4 TPI, 1.25mm = 20.3 TPI, 1.5mm = 16.9 TPI, 2mm = 12.7 TPI). If you try to install a 10AN hose end on your 8AN male fitting, they won't cross-thread or even "almost" fit together. When racers adopted AN plumbing, it soon became apparent that engineers in different industries did not work together much. If you compare the male OD in the first table to the female ID in the last table, you will note that (with the exception of 3AN and 4AN), no two AN sizes are even close enough to start threading together. Install assemblies at its normal length. Corrugated Flexible Pipe provides several benefits including being resistant to high as well as low temperature. 0000350309 00000 n
If you are building a structural project and using fittings to construct something that will never see flow through the pipe, you pick the size of pipe based on the physical strength you need. 
Fittings are a little different and slightly more complex. %PDF-1.4 To convert from psi to feet of head, see our, All text, images, layout and design Copyright 2002 - 2022 FlexPVC, Click here to buy short sections of FLEXIBLE pvc pipe, CTS fittings, including Sch 40/80 to CTS adapters, Other, less common, Large PVC Pipe Outside Diameters, Pipe Size Dimensions Sorted By Pipe Outer Diameter, Why it's important to buy Made In The USA flexible pvc pipe from FlexPVC.com, Hard copy of our Warranty, Returns & Exchange Policy.

It is quite easy to confuse circumference for diameter because they are both units of measurement relating to circles. 
Many of these internal diameter measurements are very close to those of other port types. [NOTE: Properly torquing your AN fittings is also important. People that are new to the hydraulic and pneumatic industries often ask: What is a dash size? Braided Hose For Water Line is said to be light in weight, flexible, and non corrosive due to which they do not crack. 0000434666 00000 n

ID is the abbreviation for internal (or inner) diameter. However, the fittings used for construction projects do not come in Sch 80, only sch 40. Circumference is the distance around the circle. SAE fittings look very similar to AN fittings. hose pressure hydraulic chart spiral importance assemblies DO NOT TORQUE! 0000231243 00000 n
As per ss corrugated flexible hose manufacturers India they can sustain in the temperature range of - 270degrees C to 700 degrees C. Ss Corrugated Hose also compensates for the thermal contraction and expansion in the piping system. The distance to the opposing point of the circle is the measure of the flex duct sizing for the inner diameter. -1 is 1/16, -2 is 2/16, and so on. 0000231530 00000 n

Flexible Hose Pipe displays good strength and corrosion resistant properties. This means that 6AN hose will not introduce any appreciable flow restriction in a fuel system designed around 3/8" OD rigid tubing. Ie if you have Sch 40 1" pipe, you buy Sch 40 1" fittings.

If hoses were called out using the hose OD (following the same system used for tubing), the ID of a 3/8" hose would be much smaller than the ID of a 3/8" tube.

Our affordable price and unmatched quality have made us one of the leading manufacturers of 1 Inch Corrugated Water connectors. To help differentiate between the two systems, convention has put the "AN" before the bolt size but after the plumbing size (e.g., AN4 bolts / 6AN hose).
