At APM Hexseal, we design and manufacture an expansive array of proprietary, high-performing, self-sealing hardware for use in environments ranging from average to severe. Our self-sealing Seeloc® Washers are made by bonding molded silicone rubber to specially formed stainless steel washers. They form soft and durable seals when used with traditional fasteners. Heavy-duty, Imperial, and metric varieties are available.
Types of Seeloc Washers APM Hexseal Offers:
- Metric Seeloc Washers: Our standard Seeloc metric washers are made from 18/8 stainless steel and feature a broad temperature range of -103°F (-75°C) to 400°F (204°C), internal and external pressure tolerances up to 100 psig, and a shelf life up to 25 years. They also resist dust, fungus, most acids and oils, splash, salt spray, sunlight, and ozone.
- Imperial & Heavy Duty Seeloc Washers: Our Heavy Duty Seeloc® Washers are capable of handling torque values AT LEAST 50% higher than our original Seeloc Washers. Currently available in both 1/2” (14mm) and 1” (25.4mm) O.D. sizes, these new sealing washers are perfect for a myriad of sealing requirements, from medical equipment and chemical handling, to construction equipment and food processing.
