O-Ring Applications, Failure Modes & Troubleshooting

This is the problem-solver chapter. Something is leaking, or you are speccing a seal for a real machine in a real industry, and you need the answer, not a theory lecture. Start with whichever door matches your situation:

• O-Rings by Industry: what hydraulics, automotive, aerospace, oil and gas, food and beverage, medical, water, semiconductor, and chemical plants actually run, and the traps each industry keeps falling into.
• Special Uses: drive belts, vacuum service, quad-rings and X-rings, cord stock, and the kits that keep service trucks moving.
• Failure Mode Gallery: nine failures, each with a picture, the cause, and the fix. Match your dead ring to the diagram.
• Troubleshooting: start from the symptom and work back to the root cause.
• Installation & Handling: lubrication, stretch limits, chamfers, and the assembly habits that prevent day-one failures.
• Rules of Thumb: the do’s and don’ts checklist earned from real jobs.
• Storage & Shelf Life: how long every compound lasts per ARP 5316, cure dates, and storage that stops the clock.

Design-side reading lives in Design | Engineering; compound selection starts at the Material Selection Guide. And when the page doesn’t settle it, send us the application: fluid, temperature, pressure, and size, and we will spec it with you.
