Oswald Supply Black Max Elliptical Gaskets – 6-Pack

The **Oswald Supply Black Max Elliptical Boiler Gaskets** deliver superior sealing performance compared to traditional spiral-wound gaskets, even under demanding conditions. Engineered with **foil-reinforced, exfoliated graphite and 316 stainless steel**, these gaskets provide exceptional recovery properties, sealing effectively on rough or pitted surfaces with less compressive force required. Unlike spiral gaskets, which demand near-perfect surfaces, Black Max gaskets adapt to real-world imperfections while maintaining a reliable seal.

Designed for high-pressure applications up to **2,000 PSIG (70 bar)**, these gaskets excel in extreme temperature environments—from cryogenic (-400°F) to high-heat steam applications (1,200°F). Their **anti-stick material** reduces installation effort, while the multi-layer construction ensures long-term stability. Whether for boilers, valves, or flanges, these **6-pack elliptical gaskets (3.25″ × 4.50″ × 0.50″)** simplify maintenance with easy installation and removal.
