People Also Ask: Top Industrial O-Ring Questions
Expert Answers to Your Most Common O-Ring Queries
What is the difference between NBR, Viton, and EPDM O-rings for industrial use?
NBR (Nitrile) is best for general-purpose oil and fuel resistance. Viton (FKM) excels in high-temperature and aggressive chemical environments. EPDM is ideal for steam, water, ozone, and weathering resistance but should not be used with petroleum oils.
How to choose the right O-ring material for high-temperature plant applications?
For high-temperature applications (above 150°C), Viton (FKM) or Silicone (VMQ) are the standard choices. For extreme heat exceeding 200°C, consider PTFE-encapsulated O-rings or Kalrez (FFKM). Always check the continuous vs. peak temperature ratings of your specific process.
What are the standard industrial O-ring sizes and AS568/BS1806 metrics?
Standard sizes are governed by AS568 (inch/dash numbers like -222) and ISO 3601/DIN 3771 (metric ID x CS in mm). BS1806 is the British standard for imperial sizes. We stock all standard metric and imperial dash sizes from 1 mm to 500 mm ID.
Where can I source bulk O-rings for factory maintenance across India?
You can source them directly from KELOR Krishna Industries. As leading bulk industrial O-ring suppliers in India, we offer annual rate contracts, scheduled dispatches, and Pan India delivery from our Ahmedabad hub to keep your MRO inventory stocked.
What is the standard lead time for custom molded O-rings in India?
Standard lead time for custom molded O-rings is typically 2 to 3 weeks, which includes tooling (mold creation) and production. For urgent requirements, express tooling options can reduce this to 7-10 days depending on the complexity of the drawing.
How to identify and verify the material of an existing industrial O-ring?
You can perform a burn test (observing flame color, smoke, and odor) or specific gravity testing. For precise verification, bring the failed sample to our Naroda office for walk-in identification, or send us a photo with a scale reference, and our technical team will recommend the exact compound match.
What is the minimum order quantity (MOQ) for industrial O-ring suppliers?
Our standard MOQ is 1,000 pieces per size/material, with a Minimum Order Value (MOV) of ₹50,000. However, for critical plant maintenance or emergency breakdowns, we can accommodate lower quantities from our ready stock.
Which O-ring elastomer is best for chemical resistance in processing plants?
Viton (FKM) offers excellent resistance to a wide range of acids, fuels, and hydrocarbons. For highly aggressive solvents, strong acids, or alkalis, PTFE-encapsulated O-rings or FFKM (Perfluoroelastomer) provide the ultimate chemical resistance.
Do O-ring manufacturers in India provide material test and compliance certificates?
Yes, reputable manufacturers and distributors like KELOR provide Material Test Reports (MTR), RoHS/REACH compliance, FDA certificates for food-grade materials, and USP Class VI documentation for pharmaceutical applications upon request.
How to prevent O-ring extrusion and failure in high-pressure hydraulic systems?
To prevent extrusion, use harder durometer materials (e.g., 90 Shore A instead of 70), reduce the diametrical clearance gap, or install anti-extrusion backup rings (like PTFE) on the low-pressure side of the O-ring.
