EPDM Neoprene Sealing Washers 25pcs PZRT 304 Stainless Steel M6.3x16mm

Description

Product Overview

The EPDM Neoprene Rubber Bonded Sealing Washers offered by PZRT are engineered to meet the demanding requirements of industrial and scientific environments. Each washer in this 25‑piece set features a robust 304 stainless steel core that provides structural integrity and resistance to corrosion, while the surrounding EPDM neoprene layer delivers exceptional flexibility, elasticity, and shock‑absorption. The combination of these two premium materials ensures a reliable seal that can withstand exposure to water, chemicals, temperature fluctuations, and mechanical stress. The washers are sized at an inner diameter of 1/4 inch and an outer diameter of 5/8 inch, with a thickness of 16 mm, making them compatible with a wide range of M6.3 bolts and fasteners. The product dimensions of the package are 3.07 × 2.44 × 0.63 inches, weighing just 1.23 ounces, which facilitates easy handling and storage. Designed for both professional technicians and DIY enthusiasts, these washers are suitable for applications ranging from plumbing fixtures and hydraulic systems to automotive components and heavy‑duty machinery.

Usage

These sealing washers excel in wet environments where preventing leaks is critical. They are ideal for sealing pipe joints, valve assemblies, pump housings, and any interface where water, oil, or compressed air may escape. The EPDM layer acts as a cushion that compensates for surface irregularities, ensuring a uniform seal even when the mating surfaces are not perfectly flat. In addition to water‑resistant applications, the washers perform well in chemical processing plants, where resistance to acids, bases, and solvents is required. Their shock‑absorbing properties also make them valuable in vibration‑prone installations such as motor mounts, compressors, and industrial equipment that experience frequent start‑stop cycles. The 304 stainless steel core guarantees longevity in corrosive atmospheres, extending the service life of the washers and reducing the need for frequent replacements. Whether you are assembling a laboratory apparatus, maintaining a manufacturing line, or repairing a household appliance, these washers provide the confidence of a secure, leak‑free connection.

FAQ

What is the temperature range for these EPDM sealing washers?

The EPDM neoprene material can operate effectively from -40 °C to +120 °C, making the washers suitable for most industrial temperature conditions.

Can these washers be used with non‑stainless steel fasteners?

Yes, the washers are compatible with a variety of fastener materials, including carbon steel, brass, and aluminum, as long as the bolt size matches the M6.3 × 16 mm dimensions.

How do I install the washers to achieve the best seal?

Place the washer between the mating surfaces, ensuring it is centered and fully seated before tightening the fastener. Apply even torque according to the equipment specifications to compress the EPDM layer without over‑tightening.

Are these washers reusable after removal?

While the EPDM layer can retain its elasticity after a single removal, repeated cycles may reduce its sealing effectiveness. For critical applications, it is recommended to replace the washer after each major maintenance event.

What warranty does PZRT provide for these sealing washers?

PZRT offers a one‑year limited warranty covering material defects and manufacturing errors, backed by responsive technical support to address any concerns.
