Under normal pressures the pipe joint compounds does not need a curing time. If the pressure in the lines is 125psi or higher, the recommended cure time is 4 hours before initiating pressure. Call Oatey Customer Service when in doubt.

Oatey does not have any products that will work in this application.

All joint compounds with the exception of Megaloc will not be removed easily. You should check with the materials manufacture that you are removing the pipe joint compound from first, to confirm what cleaning chemicals are compatible with their product.  Start by trying to remove the pipe joint compound with white vinegar and working your way up to acetone. Remember to always test a small out of sight area first, before damaging the finishes or affecting the integrity of materials that the pipe joint compound was adhered to. Megaloc can however be cleaned off hands and tools with a dry rag, and easily washes out of cloths with soap and water. 

All ½”, ¾” and 1” wide tapes are installed the same way. After you select the proper size of tape for your thread, you will wrap in a clockwise motion, while keeping the tape at the bottom of the thread. For ½”, ¾” and 1” pipe threads you will only need to wrap the threads in a straight pattern 3 to 5 times around the male thread, if the tape width is the same size as pipe diameter. For 1¼” pipe threads and above or when tape width is smaller than pipe size, you will wrap 4 to 5 times starting at the end of threads and working up. 

The following Oatey pipe joint compound products are approved for use in this application: Oatey Great Blue, Hercules Block, Hercules Grrip, Hercules Megaloc, Hercules Pipe Joint Compound, Hercules Pro Dope or Hercules Real-Tuff are all safe for this application. 

The following Oatey pipe joint compound products are approved for use in this application: Oatey Great Blue, Hercules Block, Hercules Megaloc, Hercules Grrip and Hercules Real Tuff. 

There are no limitations on the diameter of the pipe. You should always wrap the tape enough times around the male threads in order to fill the spigot (female threads). Any pipe sizes over 1¼” with pressure and fluids moving through it should have the male threads wrapped with tape and then the approved pipe joint compound spread over the tape.

Yes. Mega Bubble will help you locate any non-liquid leaks and will not compromise the pipe / fitting materials.

Yes. All Oatey thread sealant tapes will work on natural gas lines. Oatey does however recommend the use of yellow gas line thread tape with PTFE on all natural gas line installations, product #31403. The Oatey yellow gas line thread tape is approved by code for this application and the yellow color is a visual identifier that the correct tape was used in the application. 

Yes. All Oatey thread sealant tapes are safe to use with potable (drinking) water.

Fill the male threads in a clockwise rotation following the direction of thread pattern, or brush across the threads as long as you fill the root of thread without completely covering the crest of thread. 

We have posted a direction sheet for this process on our website in the technical bulletin and  FAQ sections.

No. The PVC cements are too aggressive and will cause probable failure to the CPVC pipe and fittings and if it was used, the joints should be cut out and replaced. If CPVC cement was accidentally used to bond PVC joints, it would not be necessary to replace them but future joints should be assembled with correct cements.

Oatey has developed this cement specifically for this application and it is UPC and NSF listed. In saying that; we do recommend that you check with your local building officials and see if they have any restrictions on its use. The UPC and IPC codes are a minimum guidelines and each city, county or health department can set forth tougher guidelines which may prohibit the use of transition cement.

We cannot support these applications although a semblance of a bond may exist. It is a violation of all plumbing codes to use cements not specified for use with materials it is being applied to for bonding purposes. These joints should be cut out and the approved transition fittings used to finish the application.

Interference fit is the pre assembly test you apply to the pipe and fitting. After pipe is chamfered you will dry fit the pipe into the fitting and you will want resistance between 1/3 and 1/2 way into the fitting. This will allow for a good bond when cement is applied. If there is no interference fit, you should not try to cement the pipe and fittings together.

All Oatey PVC and CPVC solvent cements have been tested to NSF standards and are approved with use on drinking (potable) water systems.

Oatey cements and primers have outside lab approval for lines that carry drinking water (NSF). The plumbing system carrying the water should be drained by first shutting the water off at the water meter, which is most commonly found in the basement on the front wall facing the street. If you have a home on slab, it should be in the mechanical room with the furnace and water heater. Open all faucet valves and allow the interior piping system to air dry overnight.  This will allow most of the remaining vapors from the cement and primer to dissipate and escape, air movement is a huge plus.

No. Oatey has NSF approved cement for this application called ABS to PVC Transition Green Cement. This transition cement is for applications where the interior building drain and the exterior sewer drain are made of dissimilar plastics, generally ABS and PVC. Check with your local building officials before attempting this application to insure it is approved in your municipality. 


Oatey Rain-R-Shine or PVC Flexible cements can be used for this application.

Yes. Oatey Industrial Grade CPVC and PVC low VOC cements can be used in this application. Please contact the technical department for chemical compatibility for the cements that would be appropriate for the application.


Chamfering is the act of beveling the outside end of the pipe, which you will be inserting into the fitting. This keeps the cement from being pushed out of the fitting and causing a weak bond in the joint.

Yes. The Oatey Heavy Duty cements can be used as long as the application instructions are followed.

Oatey Flowguard Gold #3194 and #3195 can be used in this application. Before starting this application make sure your local gas provider and building officials allow for the use of these products in this application.

Yes. Only if the fabric is PVC. If it is CPE, we would recommend Oateyweld. We recommend a completed application test on a small section before applying one of our products to the final assembly when it is not being used for its intended purpose.

No. It is not recommended because it takes longer for CPVC to finish the curing process necessary to complete a strong bond after the cement is applied. CPVC is also rated for hot water use which will affect cure times. PVC is not rated for hot water temperatures.

Once a joint has been properly assembled it cannot be cleanly separated without distorting or destroying the pipe/fitting. The joint if properly assembled is stronger than the pipe itself, and will have to be cut out and replaced.

No. Cleaner is only designed to remove surface dirt and grease from the pipe where as primer actually starts the chemical reaction needed to bond the pipe and fittings together.
