Premium Silicone Rubber O-Rings & Bumpers – Precision Molded for Durability
High-grade silicone rubber construction ensures superior elasticity, heat resistance (up to 230°C/446°F), and UV stability for long-term outdoor/industrial use. Neutral 2 hardness (Shore A) balances flexibility with load-bearing strength. Laser-cut edges and injection-molded precision eliminate leaks, ideal for sealing windows, automotive grommets, hydraulic systems, and DIY mold-making (compatible with Oomoo/Momentive compounds). Non-toxic, FDA-compliant material resists oils, acids, and extreme temperatures (-60°C to 230°C). Bulk-packaged for cost-effective large-scale projects—wholesale pricing unbeatable for machinery repairs, plumbing, or prototyping.
