Ultra-Drain Seals®

Clear Models

Transparent drain protection allows responders to see spills are being stopped

A spill response drain cover is one of the easiest and most effective ways to stop a spill.  But how can a responder know for sure that it's working?  Cracks in concrete and dents in grating can offer a "path of least resistance" to spilled liquids.  

An opaque spill response drain cover will not allow a visual inspection of whether or not spilled liquids are finding ways around the protection.  The Ultra-Drain Seal, Clear Model changes that. 

  • The clear material provides an unobstructed view of covered drains - enables responders to make sure a complete seal is made.
  • No more guesswork about Drain Seal effectiveness - quickly see if spills are entering the drain through cracks in the surface, imperfections in the grating, or other irregularities that can break the seal.
  • Reinforcing mesh is “sandwiched” between layers of polyurethane — increases durability and resistance to tearing.
  • Unique, urethane construction allows the pad to deform and seal off most drains — temporarily “seals” to any smooth surface.
  • Helps comply with SPCC and NPDES

Chemical Compatibility

Frequently Asked Questions

Can I leave a Drain Seal on top of the drain for long periods of time?
The Ultra-Drain Seal is made with urethane and will degrade/break down in extended UV exposure.  It is recommended that Drain Seals only be exposed for as long as required to contain and clean-up a spill.  Long-term outdoor use is not recommended.


Can you drive over a Drain Seal?  
It is not recommended that the Ultra-Drain Seal be driven over under any circumstances.  The softer nature of the material can be damaged under vehicle tires and other equipment.


How do I clean the Drain Seal?
Typically, a standard soap and water mixture is all that is needed to clean the Ultra-Drain Seal.  Once it has been cleaned it should be allowed to air dry and then returned to its original packaging.


Is the Drain Seal reusable?
Yes, the Ultra-Drain Seal is reusable provided that it has not been exposed to a chemical that has caused any degradation.


Can I cut the Drain Seal?
The Ultra-Drain Seal has reinforced tear-resistant mesh "sandwiched" between layers of urethane, cutting it is NOT recommended as it may cause the unit to delaminate.


Are custom sizes and/or shapes available?  
Yes, custom shapes and sizes are available.  Please contact our customer service department for more information.


What size Drain Seal should I use?  
For best results, use an Ultra-Drain Seal that is at least 6” larger than the outside of the grate.


What is the best way to store a Drain Seal?
The Ultra-Drain Seal should be stored in a cool, dry area in the box that it is shipped in.  Optional hard-plastic carrying cases that can be wall mounted or truck mounted are also available.  It is important that the Ultra-Drain Seal does not touch itself because, over time, the touching areas will fuse together.  This can be prevented by using the cardboard tube and plastic sheeting each unit is shipped in.


Your compatibility chart says 'NR' for the chemical that I'm using.  What exactly does that mean?  
'NR' stands for 'Not Recommended'.  HOWEVER, it is worth noting that most chemical compatibility guides (ours included) are based on a one-year immersion test.  In other words, the material being tested is completely immersed in the chemical in question.  After one year, the material is removed and checked for any degradation.  Needless to say, a spill response product is not going to be exposed to a chemical for a year.  So it's possible that the Ultra-Drain Seal will be effective against a spill of a chemical that is listed as 'NR'. The best way to know for sure is to test for yourself.  Please contact our customer service team and they will be able to send you a no-charge sample.
