It is always important to first set the toilet bowl in place before installing the wax seal; this will confirm that the toilet bolts are aligned properly, and the floor can be checked for levelness in case the bowl will need to be shimmed during installation.

Oatey and Hercules wax seals are a blend of Slack Wax (unrefined feed stock) and Micro Crystalline Wax (refined feed stock). These are used to control the properties and result in a premium finished product. 

Standard Johni-Bolts are 2 ¼” long.  They are also available in an extra-long length, which is 3 ½”.

Although stacking two wax seals on top of each other seems to be a common practice, Oatey does not recommend this application. We recommend using a jumbo or extra thick wax ring instead the stacking method. Also consider raising the flange height with one of our spacer kits.

All brands of wax rings produced by the Oatey Company are manufactured at the Oatey Omaha, Nebraska facility.

The following information is copied from our MSDS sheets posted on our website along with all our product submittal sheets. 

Steps To Be Taken In Case Material Is Released Or Spilled:

  • Cover with absorbent material; let soak and sweep up.

Waste Disposal Method:

  • Incinerate or bury (landfill) away from water supplies in accordance with local regulations.

Precautions To Be Taken In Handling And Storing:

  • None

Other Precautions:

  • None

Remember to never dump the antifreeze products into the sewer systems.


Any chemical has a certain amount of toxicity, but Hercules Cryo-Tek anti-freezes are very low. This is the statement listed on the MSDS sheets that are posted on our website that can be viewed or downloaded.

Emergency and First Aid Procedures:

  • EYE AND SKIN CONTACT: Like with all foreign material, flushing and washing with water is good safety and hygienic practice.
  • INGESTION: Low in toxicity; induce vomiting if large amounts are ingested.

The answer depends on which Cryo-Tek antifreeze is being used, and what level of freeze protection is required. For more information, see this chart.

  • Freeze point:  The temperature at which crystals begin to form.
  • Pumpable:  The temperature at which there are sufficient crystals to impede the flow of the product.
  • Burst protection:  The temperature at which pipes burst.  

  • Max output – 550 GPH 
  • 2.5 GPM @ 8' TDH 
  • Air filled motor 
  • Includes pre-filter to prevent debris from re-entering heat exchanger 
  • UL listed 
  • 25’ cord

The pump has a one year warranty from date of purchase.

The Haymaker solution is 3 times as effective on scale as vinegar, and has no foul odor.

Yes.  Use Cryo-Tek 100AL antifreeze for boilers with aluminum heat exchangers. Sludgehammer Universal Corrosion Inhibitor and Sludgehammer System Restorer & Noise Reducer is compatible with all metal heat exchangers, including aluminum.

Each strip has two pads.  One pad measures the level of propylene glycol, the other measures the level of corrosion inhibitor.  These levels should be checked as part of routine boiler maintenance.  

Virgin propylene glycol has never been used previously.  Some boiler manufacturers state in their warranties that antifreeze made with virgin propylene glycol is required or the warranty is voided.  

Recycled propylene glycol is captured and cleaned after use (mainly for de-icing aircraft). It is then considered a lower grade of propylene glycol and may still contain other ingredients even after cleaning.  

Hercules Cryo-Tek antifreeze is made only with virgin propylene glycol.

This is a patented formulation that is combined with virgin propylene glycol to:

  • Prevent corrosion
  • Prevent scale
  • Maintain proper pH levels

You should contact your local fire department or building department to find out the protocol is for the disposal of hazardous materials. 

No. This is a very harsh acid based product. If left on surfaces even when mixed in with standing water, an etching process will take place and permanently damage the finished surface of the fixture.

While the active ingredients are very similar, there are subtle differences that make them better suited for each applications.   For example:  Liquid Glug for the Kitchen uses a deodorizer designed to eliminate the smell of leftover food in the DWV system.

Spills/Leak Control: Spill area should be isolated to avoid possible exposure, and remove all ignition sources. 

For small spills; neutralize with soda ash or lime, then absorb with sand, clay or diatomaceous earth. 

Dike large spills; collect into an acid resistant container if possible otherwise cautiously dilute and neutralize with soda ash or lime, then collect or sweep neutralized material into an acid safe container for proper disposal. 
Wash the area with large amount of water.

PT 4 or PT Bio1 are both designed for this application, but PT 4 is fast acting and PT Bio1 is better cleaning.

Glug is safe and easy to use for most common kitchen sink clogs.  If you think the clog is grease related, PT Bio1 may be your best option.

The most common Clog Buster failures occur because it was inserted into the drain pipe improperly. Clog Busters must be fully inserted into the drain pipe and not into an 90 degree elbow, or Tee fitting. These fittings allow for uneven expansion and eventual failure. 

This product is an herbicide and therefore must be registered with each state’s EPA.  Some states do not allow copper sulfate to be used as an herbicide.

PT Bio1 uses bacteria blends to completely digest and eliminate grease.  PT-4 uses solvents to liquefy it and move it out of the system.  PT-4 acts faster but does not completely digest the grease, it simply moves the grease out of the system.

Glug is composed of sodium hydroxide flake.  Many other similar products use sodium hydroxide prill (little beads).  The prill is denser and has less surface area.  Unlike the flake, it does not get caught in the clog as easily and therefore can pass through the clog without dissolving it.

Oatey believes that due to the dangerous nature of Clobber; it should only be used by professionals who know how to use, handle and store the product. Clobber should never be used by an individual that is not trained, and does not understand the dangers of sulfuric acid.

Clobber is a concentrated blend of sulfuric acid and Sizzle is composed of hydrochloric acid.  Sulfuric acid is very effective at dissolving organic material, like food, grease and hair; Sizzle is used for dissolving inorganic material like mineral deposits, lime rust and scale. 

Pipe/Gasket Lube is a Non-Toxic soft paste like material used to lubricate bell joint pipe gaskets before assembly. It will not deteriorate natural or synthetic rubbers, and does not support bacteria. It will dissolve in hot water. 

Yes. This product can safely be used on rubber and synthetic O-rings, and plastic parts. This product does not contain any petroleum products.
