Thomas ★★★★★

Popped one of these on my hydraulic fitting that had been weeping for weeks — it stopped the leak on the first try. The rubber feels pliable enough to work with easily but stiff enough to hold under pressure.

Henry ★★★★★

Finally, a dash 453 that seals perfectly on my pneumatic actuator. The -40°F rating was critical for my outdoor setup, and these haven’t leaked a drop even in this cold snap.

Henry ★★★★★

The 70 durometer hardness is exactly what I needed for a snug fit on my hydraulic fitting, and they slid on without any tearing. The pack of 14 gives me plenty of spares, and I've used them up to 200°F with zero issues so far.
