If you only stocked one rubber washer material, neoprene would be the smart pick. It's the all-rounder of the rubber world — good at almost everything, great in weather, and forgiving when you're not certain what your application demands.

- Temperature range: roughly -50°F to 250°F
- Resists: weather, ozone, sunlight, refrigerants, moderate chemicals

Why people choose neoprene
Neoprene's superpower is balance. EPDM beats it outdoors, nitrile beats it on oil, and silicone beats it on heat — but neoprene does all three respectably in one compound. That makes it the lowest-risk choice for mixed or unknown conditions, and the reason it's the most common general-purpose washer material.
When to pick something else
Choose nitrile if oil or fuel is involved, or EPDM for constant outdoor water exposure. For sustained heat above 250°F or food-contact jobs, step up to silicone.
