No matter your pipe thread sealing job, we've got you covered. Oatey offers a variety of thread sealant tapes and pipe joint compound pastes. From Oatey's low-density PTFE tape to PTFE pipe joint compounds, these products can be used on all threaded pipe, valve and fitting types.

Product Information

White Plumber's Tape

Oatey plumber's tape made of virgin white PTFE provides a clean, positive seal on threaded connections for water or air fittings. Non-hardening, non-toxic, non-stick and non-flammable, it is safe for use on potable water applications.

Yellow Plumber's Tape

Manufactured especially for natural gas, propane, butane, water, oil and chemical lines, Oatey yellow plumber's tape is nonflammable and resists tearing and stretching for easy, efficient application on metal and plastic threads. It is heavier than white tape at 4 mils thick.

Joint Compound

Oatey joint compound is a non-hardening, non-separating, non-toxic paste that lubricates and seals on plastic or metal threaded joints, requiring no cure time for lines with pressure under 125 psi.

Key Features

Easy to Apply

Oatey thread sealants are simple to use and efficient to apply - Oatey plumber's tape resists tearing and stretching, and is packaged on spools in convenient dispenser boxes, while Oatey joint compound comes with a brush top applicator.

Ensures Dependable, Leak-Proof Joints

Oatey thread sealants lubricate and seal all threaded joints. Weather-resistant, flexible, low dielectric constant, chemically inert and usable at low temperatures, Oatey plumber's tapes perform over a temperature range of -450° to 500° F and up to 10,000 psi.

Versatile Applications

From low-pressure to high-pressure piping demands, from plastics to metals, as well as the market’s need for PTFE, Oatey offers pipe joint compound solutions for every type of job. Oatey PTFE tapes can be used on all threaded pipe, valves and fittings carrying acids, solvents, alkalis, steam, hot and cold water, LP gas, natural gas, oxygen and almost any chemical.

Since 1916, Oatey has provided reliable, high-quality products for the residential and commercial plumbing industries, with a commitment to delivering quality, building trust and improving lives. Today, Oatey operates a comprehensive manufacturing and distribution network to supply thousands of products for professional builders, contractors, engineers and do-it-yourself consumers around the world.
The Oatey 8 oz. All-Purpose Leak Detector is designed to form large bubbles to indicate even the smallest leaks in many types of piping applications. Detects leaks quickly on all types of tubing, valves, cylinders, pressure tanks or other systems under air, gas or oxygen pressure. Functions in -55 degree F to 160 degree F temperature range, making it great for refrigeration lines. Leak detectors are formulated to be used on the specific materials used in plumbing and won't corrode or degrade the pipe if you don't wipe the solution off after checking for leaks. The surfactants and builders in soaps can leave a corrosive residue on the pipe after you're done checking for leaks. This can cause discoloration and in rare occasions small pinhole leaks depending on the temperature and the material being run through the pipes.
  • High-viscosity formula clings to vertical surfaces

  • Can be used in a temperature range from 55 degree F to 160 degree F
  • Produces large, long-lasting bubbles to indicate leaks

      A:  Hello, Leak Detector uses a high-viscosity formula that produces large, long-lasting blue bubbles for easier detection of leaks on pipes, fittings, tanks, coils, cylinders, pressure vessels and valves. The formula is non-toxic, non-corrosive and will not freeze. Products built to last and trusted by plumbers to withstand even the toughest conditions

        A:  I've used dish soap before, and it's cheap and easy to use. It can leave a sticky film if not rinsed or wiped off completely, and some are corrosive to iron pipe. Very small leaks may not bubble up as well as this product, which will foam up. If you're only doing one or two connections, I guess you could get by the old way.

          A:  Yes, yes it has...I on the other hand do not keep "dish soap" on hand in my home.  dries gaskets and other porous materials out much more quickly than just using a mild soap bar. So, for 2 bucks, I have a bottle for leak detection I can use on just about AJYTHING, including hoses, tires and gaskets on my vehicle, and it wont dry material out so badly. I wish you good luck with you dish soap venture.

                Great Basic Checkerq
                Had to replace my water heater and wanted to make sure there was no leaks. Bubble test was as simple as it gets. It was effective, but I though it would be bubblier.

                  No LEAKS!
                  I have used this leak detector for the past 3 years and have been very pleased with it. It's easy to apply since it has the brush inside of it and it's ready to use. I do not have anything to dislike about this product. It worked well when I installed my new gas range. This product did meet my expectations. Please hit the thumbs up if this was helpful.

                    Works properly
                    Recently used when hooking up gas to water heater. The only issue I had with this product was getting bubbles when applying it to connections(picture), but that happens with any blue leak solution I have used. Immediate leak detection so a couple applications and staring at pipe for a while to make sure no new bubbles formed worked for me.

                      It works but.............. it does produce some bubbles when air is leaking, but the bubbles are small and do not last very long, so it is hard to tell if you have a leak which it the whole point of using it. I compared it to a couple of ounces of dish soap in a quart of water and that was much better for finding leaks (as can be seen in the pictures) one of the good points of this leak detector vs water and soap is that it can be used down to -55 degrees. It comes with a decent applicator in the bottle which is good, It can also be used in a spray bottle for easier application. If it made more or better bubbles I would have given it a 5 star but they are just to small and short lived to be much use.

                      Thank you for the review. Please keep in mind that dish soap has corrosive properties to certain pipe materials, so it shouldn't be used as a leak detector.

                      I have no idea if it works for the purpose intended. I intended to use it as a dye to test my toilet for leaks. Turns out this product is highly toxic. I will not be sending it into my septic system. I only wrote this review to stop the requests for a review from coming in.
