ASME A112.4.4:

Plastic Push-Fit Drain, Waste, and Vent (DWV) Fittings


This standard covers reversible push-fit drain, waste, and vent fittings intended for quick assembly of IPS schedule 40 series PVC and ABS DWV plastic pipe and fittings for applications above- and belowground operating at temperatures between 32 F (0 C) and 140 F (60 C) and specifies requirements for materials, physical characteristics, performance testing, and markings.

Unique, Patented, Reliable Connection

Easier, Faster Installation

ConnecTite joints are over 20 times faster to install than a solvent cement joint. Thanks largely to the market’s familiarity with push-fit pressure fittings, the installation is rather intuitive.

Less Downtime

ConnecTite fittings have no cure time. In comparison, a 2-inch solvent cement joint has a minimum cure time of two hours before it should be tested.

This allows a DIYer to quickly complete their DWV project with ConnecTite fittings and then spend their time doing something more enjoyable.

For a repair plumber, they can move on to their next customer in a fraction of the time, thereby increasing their revenue.

No Solvent Cement or Primer

  • Is better for human health and safety
  • Is more environmentally friendly — ConnecTite contains no VOCs.
  • Eliminates confusion over which solvent cement to use
  • Eliminates the hazardous waste disposal of out-of-date cans of cement and primer
  • Causes no mess — spilling purple primer is almost inevitable, especially for a DIYer. When this happens, there is no way to clean it up. This is of particular concern if you are making a solvent cement joint in a finished area.

Can Be Repositioned

With a ConnecTite fitting, you can simply twist the fitting into proper alignment.

This is helpful when you are using a fitting with a bend (90-Degree Elbow, 45-Degree Elbow, or Sanitary Tee).

If you have a misaligned fitting with solvent cement, the only option you have is to cut out the joint and start completely over.

Reversible & Reusable

If pipe is cut too short or too long, you can remove the pipe from the ConnecTite fitting, cut your pipe to the correct length, and then reuse the same ConnecTite fitting up to three times.

Again, with solvent cement, your only option is to cut out the joint and start completely over.

Compatible With Both PVC and ABS

ConnecTite fittings can be used as a transition fitting as it works with Schedule 40 OD plastic pipe.

Does Not Require Any Tools

Unlike push-fit pressure fittings, ConnecTite fittings do not require a tool for reversal.

Standard DWV Diameter

ConnecTite fittings will fit in the same places as a solvent cement fitting of the same diameter.

Made in USA

Like all Charlotte Pipe products, ConnecTite fittings are made in the USA.
