Tubos Vent Pipe Extension

Tubos are prefabricated plumbing vent pipe extensions and the fastest, strongest, and most cost affective method for extending plumbing vent pipes during Re-roofing operations.

Tubos are made with an integral 6 in. long joint splice sleeve insert at each end, allowing for an Tubos unit to be cut and used to extend two vent stacks

Features and Benefits:

• Installs in three easy steps: Measure, Cut length, seal in place with caulk
• Compatible with both Cast Iron and PVC vent pipes and accomodates the majority of vent pipes
• Properly installed Tubos will not leak
• Installs with common tools
• Each 28 in. unit allows for up to tow vent pipe extensions

2", 3", 4" & 5" Tubos sold per unit

1 unit = 2 Tubos (1 Unit is cut in half to create 2 Tubos) 

Units are sold individually

Box quantities:

• 2" = 18 units per box
• 3" = 12 units per box
• 4" = 9 units per box
• 5" = 6 units per box

Ease of Installation:

No special tools are required to size and install TUBOS® securely into openings of existing plumbing vent pipes. Standard hand tools (tape measure, manual or portable battery powered saw, caulk gun) are all that is needed for installation.

Design Simplicity:

TUBOS® are manufactured for use with standard diameter vent pipes. TUBOS® are prefabricated with integral six-inch long pipe joint splice sleeve inserts at each end of every unit.

Economical:

Each TUBOS® can be used for two installations. After one end of the TUBOS® is cut and installed, the opposite end can be retained for future installation at another pipe of the same diameter. No fabrication time and minimal installation labor lets you quickly get on with your project.

Average time to install:

3 mins.

Fits in PVC or Cast Iron pipes

• Place your Tubos in the existing vent stack
• Measure and mark height required by code
• Cut at your mark
• Put sealant between Tubos and existing pipe
• Place your lead boot over pipe, or seal directly to TPO/PVC roof
• Completed, with another Tubos left over for the next application

Frequently Asked Questions

Q: Why can't I just use couplings and pvc piping?
A: You can not buy pvc couplings that will fit on a cast iron pipe (inside or out) that will convert to fit onto pvc.

Q: What about the no hub couplings that have hose clamps on either sides?
A: When using those you have to use a bigger lead boot to fit it, which would then cost more than using a Tubos and you would have to squeeze all the extra lead into the smaller existing pipe. Plus send a worker to pick up the couplings, Tubos comes with all your supplies to the job.

Q: What if the pipes existing on the roof are pvc already?
A: You will still have to use outside couplings, therefore using a bigger more expensive boot. Also, pvc is a new method for plumbing ventilation, 99% of your reroof jobs will be cast iron.

Q: Can't I just get two different size pvc pipes and glue them together like what appears to be with Tubos?
A: The inside and outside diameter of Tubos is one of a kind. This size pvc can not be found anywhere else. The purpose for our measurements is so the insert can fit into a cast iron pipe and pvc while the outer part of the Tubos is wide enough to sit ontop of a pvc pipe without falling down into it.
