Need a surface mount seal for chemical cabinet door

In summary, if you are looking to reduce odors from a garage, you might consider a small shed or cabinet outside, or better yet, ventilation.

TL;DR Summary
Trying to build a mini cabinet to hold chemicals and small engine fuel containers to minimize odor. What type of seal for the door will work?
I want to build a mini chemical cabinet to try to eliminate odors in my garage as my wife thinks the car interior now smells. The chemical resistant rubber strip sealant is crazy expensive, but as the intended use will just be fumes with no actual chemical or fuel contact to the seals, can I use standard, or at least a cheaper material for a surface mounted strip sealer around the door? Will the fumes be enough to breakdown the material of non-chemical resistant seals over time? If so how long might a standard rubber seal last?

Welcome to PF.

Maybe vent the cabinet to the outside of the building. Without a vent, the air in the cabinet will become saturated, and so diffuse more quickly, into and through the door seals.

Keep the cabinet as cool as possible, by placing it low down, on or near the floor, on the coolest side of the building. That will reduce the evaporation rate of the contents. Fuel vapour is a hazard in a closed garage because it settles low down in the space.

Consider a minimum power extractor fan. The concentration of vapour in the cabinet could be reduced by a continuous flow from the garage, through the cabinet, to the outside of the building. Vapour in the garage space would also be removed by that extractor fan, through the cabinet door gap, or through a vent in the cabinet. Better cabinet door seals would reduce that advantageous through flow.

Can you instead just place a small storage shed/cabinet outside in the shade next to your house? That will keep the odors out of your garage, and any odors will quickly dissipate outside once released from the shed.

Fridge-door type magnetic seals ? Plus cabinet vent to outside with riser chimney and 'cap'...

It may depend on the country and the local regulations, but as I recall, proper ventilation might be required for cabinets holding hazardous chemicals.

As it was hinted before, what an airtight cabinet do is to retain all the 'stuff' inside and blow it all in your face when you open it.

I too recommend an outdor unit, or at least outdoor ventilation.

An anecdote---my wife tends to get bothered by minutiae when I make a purchase she doesn't agree with or didn't know about. "Your new mower smells like gasoline and makes the garage stink" is something I've heard before, and you can insert "pesticide sprayer", "weedeater", "diesel generator', or "new gas can" with the same complaint. I only mention this a little tongue in cheek as maybe the issue isn't the odor...

As far as the technical, trying to enclose volatiles in a cabinet is probably not a great idea, especially if flammability is a concern. Eventually in a 'sealed' cabinet..... the vapor pressures from all the leakages will--eventually--equilibrate. This can give you a combustible gas mixture in the cabinet, depending on what is stored, the temperature, and if not climate-controlled is fairly unpredictable, especially with mixed storage.

Generally, ventilation is the easiest cure for volatiles to prevent the accumulation of vapors to hazardous, or ignitable levels..

Ventilation may not just be the fix, it could be be regulatory or best practice/insurance required, depending on the location--all the flammable cabinets I've purchased in the last 15 years were ventilated and the vents had flame arrestors in them to prevent internal and external fires propagating.

I'd suggest outdoors with no sealing using commercially available cabinets, if possible.

FAQ: Need a surface mount seal for chemical cabinet door

What materials are best for a surface mount seal on a chemical cabinet door?

The best materials for a surface mount seal on a chemical cabinet door are typically EPDM (ethylene propylene diene monomer) rubber, silicone, and Viton. These materials offer excellent chemical resistance, durability, and flexibility, making them suitable for environments where they may be exposed to various chemicals.

How do I install a surface mount seal on a chemical cabinet door?

To install a surface mount seal, first clean the surface where the seal will be applied to ensure it is free of dust, grease, and other contaminants. Measure and cut the seal to the required length. Peel off the adhesive backing and carefully press the seal onto the door frame, ensuring it aligns properly and creates a tight seal when the door is closed.

What are the benefits of using a surface mount seal for a chemical cabinet door?

Using a surface mount seal for a chemical cabinet door provides several benefits, including improved containment of hazardous chemicals, enhanced protection against leaks and spills, reduced exposure to harmful fumes, and increased safety for personnel. It also helps maintain the integrity of the storage environment by preventing the ingress of dust and other contaminants.

How do I choose the right size and shape of a surface mount seal for my chemical cabinet door?

To choose the right size and shape of a surface mount seal, measure the dimensions of the door frame and the gap that needs to be sealed. Consider the type of chemicals stored and the level of sealing required. Look for seals that match these specifications and are designed for chemical resistance. Consulting with a supplier or manufacturer can also help you select the appropriate seal for your specific needs.

Can a surface mount seal withstand exposure to various chemicals?

Yes, a surface mount seal can withstand exposure to various chemicals if it is made from appropriate materials such as EPDM rubber, silicone, or Viton. These materials are known for their excellent chemical resistance and durability, making them suitable for use in chemical storage environments. Always verify the chemical compatibility of the seal material with the specific chemicals stored in your cabinet.
