Our take on the Silicone O-Rings, 12mm OD 9mm ID 1.5mm Width VMQ Seal Gasket for Compressor Valves Pipe Repair, White, Pack of 50

These are 50 white silicone (VMQ) O-rings with a 12mm outer diameter, 9mm inner diameter and 1.5mm cross-section. The 50 durometer silicone holds a seal from -22°F to 392°F and resists ozone, weather, detergents and salt, so it suits hot-water, gas and appliance sealing better than plain nitrile rings, which top out around 250°F. The thin 1.5mm cord makes them a light-duty seal for small valves, compressors, coffee machines and plumbing fittings, not for high-pressure hydraulic work. Buyers choose silicone over nitrile for heat and outdoor exposure, and over fluorosilicone when fuels and oils are not involved.

About the Silicone O-Rings, 12mm OD 9mm ID 1.5mm Width VMQ Seal Gasket for Compressor Valves Pipe Repair, White, Pack of 50

These round silicone (VMQ) O-rings seal against pressure and fluid between cylindrical, overlapping mating surfaces. They have a durometer of 50 and work across a temperature range of -22°F to 392°F (-30°C to 200°C).

The silicone resists ozone, weather, detergent, salt and high molecular weight chlorinated aromatic hydrocarbons. It suits sealing jobs involving high temperatures, insulation or gases.

Typical uses include engines, flanges, valves and cylinders. They are also used in gas compressors, heat exchangers, boilers, filters, blenders, coffee machines, plumbing, doors and windows, household appliances and electronic instruments.

Questions and answers

Will these handle hot water and steam?
Yes for temperatures up to 392°F. Silicone is a good choice for hot-water and low-pressure steam seals, but keep them out of high-pressure steam lines.
Can I use them with oil or fuel?
No. Silicone swells and softens in petroleum oils, gasoline and many solvents. Use nitrile or Viton rings for those.
How do I confirm 12mm OD and 9mm ID fit my part?
Measure the groove the ring sits in, not the old ring. The groove should be about 9mm across the inner seat and the ring should compress slightly when the parts close.
What is the 50 durometer rating mean for me?
It is a soft silicone, roughly half the hardness of a typical 70 durometer ring. That seals well on light, even flanges but deforms under high pressure.
What comes in the pack?
50 white silicone O-rings, each 12mm outer diameter, 9mm inner diameter and 1.5mm thick.
