V-Band Flange and Clamp Dimensions — 304 Stainless, Mild Steel, MS/SS Combination

V-BAND FLANGE DIMENSIONS — 304 STAINLESS, MILD STEEL, MS/SS COMBINATION

Selecting the right V-Band Clamp, V-Band Flanges, and full V-Band Assemblies can be pretty easy when starting a new project — quality, material type, price and availability are the determining factors. However, choosing the "right" replacement V-Band Clamp or V-Band Flange can actually be harder than one might think. A countless number of manufacturers today are offering OEM and aftermarket turbo housings, merge collectors, and exhaust components with v-band flange connections and it can sometimes feel almost impossible to find the "right" muffler band clamp or v-band flange size for your application.

Due to the wide variety of manufacturers using v-band style connections today, we're seeing less "standardization" when it comes to v-band flange and clamp dimensions. The lack of standardization means that there might be 10 or more of the same inner diameter flange with extremely different exterior dimensions available. These physical differences will prevent the flanges from seating together properly and won't allow the clamp to create an air-tight, leak-free seal. This is the leading cause of difficulty that most customers face when finding a replacement component for an existing application. The second cause of difficulty that most customers—and even component manufacturers like ourselves—face is that many OEM and aftermarket manufacturers are not able or willing to provide full dimensional details for their v-band flanges. This means that a simple compatibility check requires countless measurements, example photos, and many frustrating phone calls or emails. While we aren't yet able to create a comprehensive v-band compatibility chart — which would require gathering every manufacturer's dimensional details for every v-band clamp or flange they produce or utilize — we are able to provide the key dimensional details of our brand of Stainless V-Band Clamps and V-Band Flanges.

Below are tables containing the dimensions of our 304 Stainless "Standard" style V-Bands, our Mild Steel V-Bands, and our Mild Steel/Stainless Combination V-Bands. All of these V-Band Flange types are compatible with each other! There are three main dimensions to consider when selecting a V-Band Flange or Clamp — the matching tube size (OD) material, the overall diameter of the flange itself, and the apex width. The apex width is the measurement of the flat area at the bottom of the "V" shaped retainer of a v-band clamp. The apex width measurement provided in the tables below is based on a single flange and should be doubled, when using two matching flanges, to determine the overall apex width requirements of a v-band clamp.

"STANDARD" STYLE V-BAND FLANGES & CLAMPS

Ace Race Parts V-Band Assemblies are precision CNC machined in an ISO 9001 certified facility and feature a 304 Stainless Steel V-Band Clamp and a set of "Male/Female" interlocking style V-Band Flanges. Stainless Steel V-Band Clamps and Flanges are an affordable and durable type of clamping system that is suited for high performance automotive, diesel, marine and industrial applications.

Our "Male/Female" interlocking style V-Band Flanges utilize an interlocking seating surface to ensure a leak-free seal without the need for a gasket and provides an easy way to align the flanges during installation. The interlocking seating surface, the area where the two flanges meet within the clamp, makes fitment and installation a breeze even when in the tightest of areas.

The weld side of our 304 Stainless V-Band Flanges are CNC machined with a counterbore to allow the matching tube size material to slip into the V-Band Flange and be welded in place with the proper alignment. The V-Band Flange's counterbore is machined to be 0.065" wide and allows for the inside diameter (ID) of 16 gauge wall thickness tubing to align perfectly with the ID of the V-Band Flange without any restrictions or reductions.

MILD STEEL V-BAND FLANGES & 304 STAINLESS CLAMPS

Like our "Standard" style V-Bands, our Mild Steel V-Band Flanges are precision CNC machined in an ISO 9001 certified facility and feature a 304 Stainless Steel V-Band Clamp and a set of Mild Steel "Male/Female" interlocking style V-Band Flanges. Stainless Steel V-Band Clamps and Flanges are an affordable and durable type of clamping system that is suited for high performance automotive, diesel, and industrial applications.

V-BAND FLANGE DIMENSIONS — MILD STEEL 

MILD STEEL/STAINLESS COMBINATION V-BAND ASSEMBLIES

For applications where an Mild Steel Flange and a Stainless Flange are required, we offer a "Combination V-Band Assembly" that features a "Male" Mild Steel Flange and a "Female" 304 Stainless Flange. Should you require a "Female" Mild Steel Flange and "Male" 304 Stainless Flange we are able to offer that option as well. Like our other V-Band Flanges and Clamps, our Mild Steel/Stainless Combination V-Band Assemblies are precision CNC machined in an ISO 9001 certified facility and feature a 304 Stainless Steel V-Band Clamp. 

MILD STEEL/STAINLESS COMBINATION V-BAND FLANGE DIMENSIONS

Please note, the individual flange dimensions for the items in the following table can be found in the above tables. All "Standard" style, Mild Steel, and Mild Steel/Stainless V-Band Flanges utilize the same overall dimensions.
