Victoria ★★★★★

The 90 durometer hardness is exactly what I needed for a high-pressure hydraulic fitting on my compressor. These Viton rings seat firmly without deforming, and the 150-count pack means I have plenty of spares for future rebuilds.

Natalie ★★★★★

I’ve been through two batches of these in a hot sealing setup where cheap rings melted in weeks, and the 90 durometer Viton is holding its shape without any hardening. The 1.299" ID fit my grooves perfectly, and knowing they’ll take up to 400°F gives me real peace of mind on the line.

Michael ★★★★★

Put them into a high-temp pneumatic valve that kept blowing softer rings; these Viton FKM ones have held up for three weeks without a leak despite the valve running near 350°F. The 1.299" ID fit the groove perfectly right out of the bag. Definitely saved me from having to reorder a different size.
