PVC Pipes manufacturers

There are several types and qualities of PVC pipes that are used for industrial and residential projects.

PVC Pipe Size Dimensions Chart

PVC products are adaptable with most Schedule-based PVC pipe systems.  To provide supplementary support, the following tables outline the physical dimensions and pipe diameter of each PVC Pipe Size that will work with FOR PVC products. Each of the subsequent dimensions are detached by Schedule in each table. Refer to the diagram below for an explanation of each measurement.

Important: PVC Schedule

PVC Schedule (abbrev. SCH or Sch.) is the thickness of the PVC pipe wall. The most common Schedule is 40, but Schedule 80 PVC is also available.  As the schedule gets larger the pipe wall bring thicker from the outside in, so the inside hole (bore) of the pipe bring smaller.

PVC internal-fit products, such as Internal bubble Caps, Adjustable Elbows and Internal Couplings are only adaptable with Schedule 40 PVC pipe. All PVC appliance Grade PVC pipe is Schedule 40.  Our internal-fit products will not work with PVC Schedule 80, as the inner diameter of 80 Schedule PVC is much smaller than PVC Schedule 40.

PVC Pipe is analyze by the Inside Diameter (ID) of the pipe.  This measurement is accepted as ‘Nominal’ which means in-name-only, or a ascribe name.  One of the issues experience with many of our customers is that they struggle to measure the Outside Diameter (OD) of the pipe, which will give a completely different (and larger) PVC pipe dimension.  If you choose to measure the outside diameter of PVC pipe:

  1. Take your OD measurement and look in the second or third column (Actual OD) of each table down.  
  2. Once you find your pipe OD, look to the left-most column (Pipe Size).  This will be the nominal pipe size, or the size of fittings you want to order.

PVC Schedule 80 Sizes Table

Schedule 80 PVC pipe is only compatible with PVC external-fit products. PVC internal-fit products, such as Internal arcade Caps, Adjustable Elbows, Internal Couplings and other products that fit inside of the PVC pipe will not work with SCH 80 PVC as a result of the smaller internal diameter.

PVC Thin wall Sizes Table

Thin Wall PVC pipe is only compatible with PVC external-fit products. PVC internal-fit products, such as Internal arcade Caps, Adjustable Elbows, Internal Couplings and other products that fit inside of the PVC pipe will not work with Thin Wall PVC due to the larger inner diameter.

Not all sizes are available in Thin wall PVC pipe.

C PVC Pipe

C PVC pipe, also known as Copper Tube Size (C T S) plastic pipe uses a different measurement system and is not compatible with PVC products..

PVC vs. C PVC Incompatibility

All PVC Products are designed to fit Nominal Pipe Size (NP S) size, white, Schedule 40 PVC pipe. Nonetheless, many hardware stores and home centers carry a different style of pipe called C PVC, also known as Copper Tube Size (CT S) plastic pipe, which is not appropriate with PVC and other brands of PVC fittings.

C PVC vs.PVC comparison

I ordered (1/2, 3/4 or 1 in.) fittings from PVC, but they don’t fit my pipe?
Check to see if the pipe you are trying to use is C PVC. You can do this by checking the color of the pipe: C PVC is a gold/yellow/tan color, whereas Schedule 40 PVC plumbing pipe is a boring white. Also, markings on the pipe with the following composition or names will be present for C PVC:

C PVC
CT S or (Copper Tube Size)
C PVC Pipe Markings

If the above are not marked on your PVC pipe, you may have ordered the incorrect size for your Schedule 40 PVC pipe. In that case, please see our Important PVC Pipe Size Information.

Whats different about C PVC vs. PVC and why can’t I use it?

C PVC was designed as a reinstatement for copper plumbing tubing, with a water potable and less expensive plastic solution. It is arrange to fit into the compel same holes and point where existing copper pipe is being replaced, so it has a smaller outside diameter (OD) than common white, Schedule 40 plumbing grade PVC. Since C PVC pipe uses a different measurement system and is smaller than their Schedule 40 complement, it is not compatible with PVC fittings and accessories.

C PVC to the Schedule 40 PVC pipe of the correspondent size. If you have not reduce your pipe, most home centers and hardware stores will allow you to exchange your C PVC pipe for the Schedule 40 equivalent size. This is usually the less extravagant different than returning your items to PVC, as we do not carry C PVC compatible products.
