Can I Use Oatey Medium Clear PVC Cement On CPVC?

Have you ever thought about Can I Use Oatey Medium Clear PVC Cement On CPVC? Running to the hardware store often when you don’t have something you didn’t realize you needed is one of the most aggravating aspects of home improvement projects. During a plumbing job, you might discover that you’re using PVC pipe and only have CPVC cement in your toolkit.

Can I Use Oatey Medium Clear PVC Cement On CPVC?

Yes, but only if CPVC cement is used on PVC pipes. You can’t put PVC cement on CPVC pipe the other way around. Its medium body fills gaps well and is simple to apply with the provided in-lid dauber. All schedules and grades of PVC, ABS, and CPVC pipe and fittings up to 6 in. can be solvent welded using this milky-clear, low VOC all-purpose cement.

What Is The Formulation Of PVC Solvent Cement?

Low molecular weight PVC resin is mixed in ketonic solvents. Usually, a mixture of Ethyl methyl ketone and cyclohexanone forms PVC solvent cement for joining PVC pipes. A little amount of fumed silica is also modified to make the solvent dense enough to prevent it from leaking or being squeezed out of the joint. The solvent cement has roughly 20-30% of solids.

How Is The PVC Solvent Cement Made?

Let me preface the formulation of PVC solvent cement by stating that PVC cement is used in a variety of house renovations, ranging from plumbing to large-scale bathroom or kitchen installations.

PVC pipes necessitate using a special glue known as PVC solvent cement. Because this is a chemical compound, making it a little more complicated. It is, however, a well-blended mixture of sand and cement. It will be a 50:50 split.

The standard formulation of PVC solvent cement is 15 percent tetrahydrofuran, 25 percent cyclohexanone, 16 percent methyl ethyl ketone, 30 percent acetone, 11.5 percent – 12 percent polyvinyl chloride, 2 percent – 2.5 percent silica, and 0.03 percent solvent-soluble acrylic copolymer associative thickener, according to a patent available on Google.

The compound is then cured for various amounts to get the desired shear strength. A curing time of 16 hours, for example, may result in the sheer strength of 500 psi. The company’s PVC solvent cement recipe has remained mostly unchanged.

It is, nevertheless, the strength that must be protected. PVC solvent cement should always be purchased according to the requirements. Buying the potential product from a reputable manufacturer like Finolex will provide the necessary durability without sacrificing quality.

What Bonds PVC To Cement?

You’re presumably referring to the adhesive that holds PVC to concrete. PVC usually adheres well to concrete. If a PVC pipe is going through a concrete wall as part of a water-retaining structure, you’ll need to employ a puddle collar constructed onto the pipe or a hydroswelling tape wrapped around the pipe where it is going through the wall.

When water comes into touch with the tape, it expands and prevents seepage between the cement and the PVC pipe. The PVC concrete bond is critical in this case. It’s a good idea to roughen the texture of a PVC pipe going through a wall so it adheres better to the concrete.

How Is PVC Solvent Cement Made?

Stabilizers, fillers, and CPVC resins are the major components of PVC solvent cement. It’s blended in a specific ratio. This substance should not be confused with glue. Glue, on the other hand, is an entirely different animal. The solvent’s primary function is to accomplish the following two goals:

  • CPVC resins dissolving
  • In the preparation of the fitting’s and pipe’s surface

The entire material’s molecular working is pretty fascinating. When PVC solvent cement is put to the pipe’s top layer or surface, it loosens the molecular structure and dissolves it. A taper in the socket generates a grip, ensuring no gaps are left behind. As a filler, the material is excellent. In addition to all of this, the stabilizer is critical.

Using a stabilizer extends the solvent’s shelf life and modifies its characteristics. Some stabilizers have specific properties that protect them from oxidation and heat. For the production of PVC solvent, there is a particular formula. It would make up around a quarter of the total solid in a perfect world.

If you’re seeking this item, go with a better company. For stability and longevity, one of my pals purchased a Finolex product.

What Is CPVC Solvent Cement?

Before I respond to your question, let me explain what CPVC is. Chlorinated Poly Vinyl Chloride, or CPVC, is a hard and robust thermoplastic commonly used in cold and hot water applications.

The pipes that transmit this hot and cold water are made of CPVC, and CPVC solvent cement is used to connect the pipes’ joints. The goal is to dissolve the CPVC resins and prepare the surface of the fitting or pipe.

When CPVC solvent cement is applied to the top layer of pipe or fitting material, it loosens the molecular structure and dissolves it. The fitting socket’s taper aids in creating interference between the fitting and the pipe.

These surfaces fuse in the final stage by filling in the holes in the system. The finest thing about this fusion is that it is regarded as one of the most powerful.

Because fusing occurs at the molecular level, the entire system seems to be one after evaporation. I’ve utilized Finolex’s CPVC solvent cement because of the high quality it provides. It works as a stabilizer and aids in degradation by inhibiting the oxidation of the surface.

Can You Use Solvent Cement On A PVC Pipe?

Yes, solvent cement is an excellent choice for a PVC pipe since it is easy to mix, heals quickly, and has high strength. It’s a simple, low-cost, and quick way to combine uPVC pipes and fittings. When done correctly, it generates robust, leak-proof junctions.

Solvent Cement’s working principle is as follows: the solvent ingredients enter, soften, and swell the mating plastic surfaces, causing the plastic pipe to soften and swell.

Swelling continues until the spaces between the pipe and fitting walls are closed, at which point the pipe and fitting cure and fuse together to form a tight weld. The pipe and fitting cure into a single piece of plastic as the solvents dissipate.

These types of couplings are permanent and have high tensile strength. They are typically used for water main service pipes and PVC and uPVC plumbing installations.


So, Can I Use Oatey Medium Clear PVC Cement On CPVC?  PVC is bonded with an adhesive that chemically bonds the pieces together and fills in the gaps to seal the surfaces. The ability of the cement to tolerate pressure, stress, temperature, and chemical exposure limits the joint’s physical strength and sealing qualities.

In contrast, CPVC is linked by fusing, chemically welding, or melting the close-fitting CPVC components to form a junction that relies on CPVC’s strength, sealing, and chemical qualities.

Although CPVC can be bonded using cement, the joint’s strength will weaken and eventually fail. Substituting an adhesive for a fusion-required application is never a good idea.

Frequently Asked Questions

Is it possible to put clear PVC cement on CPVC?

This means that traditional PVC cement won’t work as well on CPVC. Because there is no unique “CPVC to PVC adhesive,” chemically bonding CPVC and PVC requires solvent cement and primer that can properly bond CPVC pipe.

Is it possible to use PVC adhesive on CPVC fittings?

When working with CPVC piping, use a multipurpose PVC/CPVC adhesive or a CPVC glue; PVC glue will not adhere to CPVC effectively, resulting in leaks or breakage. Pipes made of CPVC can sustain hot water temperatures up to 180 degrees Fahrenheit. Using a fine-tooth saw, cut the CPVC pipe to size.

What is the difference between white and grey PVC?

Plumbing PVC pipe is often white, while electrical conduit PVC is typically gray. These are the standard colors, but you may also purchase PVC pipes with chemical additives applied during the manufacturing process to produce a variety of colors.

How can I tell if my pipe is made of CPVC?

PVC pipes come in various colors, including white and dark gray. The color of CPVC is off-white, light gray, or yellow. Technical details are provided on the side of both pipe types for simple verification. Both plain and bell ends are offered for both pipe types.
