Description
Product Overview
The Stainless Steel Neoprene Sealing Washer Kit from Marine Bolt Supply is engineered for professionals who demand reliability in harsh environments. Constructed from Type 18‑8 stainless steel, each washer offers exceptional resistance to rust, saltwater, and chemical exposure, ensuring a long service life even when subjected to continuous moisture and temperature fluctuations. The neoprene bonded layer adds a flexible, compressible seal that conforms to irregular surfaces, preventing fluid leakage and protecting threaded connections from corrosion. With a total of 190 flat washers, the kit provides a comprehensive range of sizes, all standardized at a 0.5‑inch outer diameter, making it an ideal solution for a variety of fastening applications across marine, automotive, and industrial sectors.
Every washer in the assortment is precision‑machined to tight tolerances, guaranteeing a consistent thickness and a uniform sealing surface. This uniformity reduces the risk of over‑tightening and uneven load distribution, which can otherwise lead to premature wear or component failure. The flat head design simplifies installation, allowing the washer to sit flush against mating surfaces, while the stainless steel composition maintains structural integrity under high‑stress conditions. The kit’s compact packaging, measuring 7 × 4.25 × 1.5 inches and weighing just 10 ounces, makes storage and transport effortless for on‑site technicians and workshop inventories alike.
Beyond its mechanical advantages, the kit reflects Marine Bolt Supply’s commitment to quality control. Each batch undergoes rigorous testing for dimensional accuracy, tensile strength, and corrosion resistance, adhering to industry standards for marine hardware. The inclusion of a full assortment of sizes eliminates the need for multiple orders, reducing lead times and inventory costs for businesses that rely on rapid turnaround. Whether you are sealing a boat hull, securing a hydraulic line, or reinforcing a structural joint, this washer kit delivers the performance and durability required for mission‑critical applications.
Usage
Designed for versatility, these neoprene bonded sealing washers excel in environments where water intrusion, vibration, and temperature extremes are common. In marine applications, they are frequently employed to seal deck fittings, hatch covers, and through‑hull penetrations, where a reliable seal prevents water ingress that could compromise vessel integrity. The washers also serve as effective spacers and load distributors in engine mounts, propeller shafts, and fuel line connections, absorbing shock and reducing wear on adjacent components.
In the automotive sector, the kit is valuable for sealing brake caliper bolts, suspension joints, and transmission housings. The neoprene layer’s elasticity accommodates slight misalignments, ensuring a tight seal even as parts expand and contract during operation. For industrial machinery, the washers are used to protect pneumatic and hydraulic fittings, electrical conduit connections, and structural steel assemblies from corrosion and leakage, extending equipment lifespan and minimizing maintenance downtime.
Installation is straightforward: clean the mating surfaces, position the washer, and tighten the fastener to the recommended torque. The flat design allows the washer to sit evenly, while the neoprene bond creates a gasket‑like seal without the need for additional sealing compounds. This simplicity reduces installation time and eliminates the risk of over‑application of sealants, which can cause chemical incompatibility or mess.
Because the kit includes a full range of sizes, technicians can quickly select the appropriate washer for any bolt diameter, streamlining the workflow on busy job sites. The consistent 0.5‑inch outer diameter ensures compatibility with standard fasteners, while the variety of inner diameters accommodates different thread sizes, making the kit a one‑stop solution for diverse sealing needs.
Why Choose Us
Marine Bolt Supply has built a reputation for delivering high‑quality fastening solutions that meet the rigorous demands of marine and industrial professionals. Our Sealing Washer Kit stands out because it combines premium materials, meticulous manufacturing, and comprehensive testing into a single, convenient package. The Type 18‑8 stainless steel used in each washer is sourced from reputable mills, guaranteeing uniform alloy composition and superior corrosion resistance compared to lower‑grade stainless steels.
Our commitment to durability is reflected in the neoprene bonding process, which fuses the sealing layer directly to the metal surface, eliminating the possibility of delamination under stress. This bond creates a resilient barrier that maintains its sealing properties even after repeated cycles of compression and decompression, a critical factor for applications subject to vibration and dynamic loading.
Customer support is a cornerstone of our service model. Should you encounter any issues with the product, our technical team is available to provide guidance on proper installation, torque specifications, and troubleshooting.

FAQ
What size washers are included in the kit?
The kit contains 190 flat washers, all with a 0.5‑inch outer diameter. The inner diameters vary to fit standard bolt sizes, providing a complete range for most fastening applications.
Can these washers be used in freshwater as well as saltwater environments?
Yes. The Type 18‑8 stainless steel construction offers high resistance to both freshwater and saltwater corrosion, making the washers suitable for a wide variety of marine and inland water projects.
Is the neoprene layer compatible with all types of fluids?
The neoprene bonded layer is chemically resistant to most common automotive, hydraulic, and marine fluids, including oil, coolant, and fuel. However, for highly aggressive chemicals, we recommend verifying compatibility with the specific fluid.
How do I determine the correct inner diameter for my bolt?
Measure the bolt’s shank diameter with a caliper or refer to the bolt’s specification sheet. Match the washer’s inner diameter to the bolt size to ensure a snug fit without excessive play.
What is the recommended torque for installing these washers?
Torque values depend on the bolt size and material. As a general guideline, follow the manufacturer’s torque specifications for the fastener you are using, typically ranging from 5 Nm to 30 Nm for most applications.
