Item No. RGS-010
Engineered for industrial-grade fastening applications, our NBR conical rubber washers for M16 bolts create a high-integrity airtight and liquid-tight seal between the fastener head and mating surfaces. The tapered conical design conforms perfectly under compression, bridging surface imperfections to prevent fluid leaks while providing reliable vibration insulation.
Superior Anti-Aging & Oil Resistance: Made from high-quality Nitrile Butadiene Rubber (NBR), these washers offer outstanding resistance to oil, grease, water, and mechanical wear. They withstand harsh environmental conditions and stand the test of time without hardening, cracking, or degrading.
Airtight & Leak-Proof Conical Seal: The precision conical geometry distributes clamping force evenly when torqued. Under compression, the rubber flows into micro-gaps to deliver a long-lasting, leak-proof seal around heavy-duty M16 bolts.
Vibration Damping & Surface Buffer: Functioning as a resilient cushion, the NBR rubber isolates structural vibration, reduces operational noise, and prevents stress cracking on painted or sensitive surface coatings.
Quick & Easy Push-Fit Installation: Designed for seamless pairing with standard M16 screws and bolts, these gaskets allow for rapid installation and convenient, non-destructive disassembly during routine equipment maintenance.
Heavy Machinery & Equipment: Flange sealing, cover plate fastening, and engine/pump housing bolt seals.
Industrial Piping & Vessels: Leak prevention for M16 threaded connections in fluid handling systems.
Structural & Outdoor Fasteners: Weatherproof and vibration-isolated bolting for steel structures and enclosures.

Standard: Goods are typically supplied in about 20-25kg/carton.
Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
What makes a conical rubber washer better than a flat rubber washer?
A conical (tapered) washer directs clamping pressure inward toward the bolt shaft when compressed. This creates a superior, localized 360-degree seal around the M16 thread and bolt head, making it significantly more effective at stopping high-pressure fluid or air leaks than a standard flat washer.
What are the main benefits of using NBR rubber for M16 conical washers?
NBR (Nitrile) offers excellent resistance to petroleum-based oils, fuels, grease, water, and hydraulic fluids. It also exhibits high tensile strength and superior anti-aging properties, ensuring the washer remains elastic and leak-proof over years of heavy industrial service.
Can these M16 conical washers absorb machine vibrations?
Yes. The elastic NBR compound acts as an effective damping buffer between the metal bolt head and the mounting surface, absorbing mechanical vibrations, reducing noise, and preventing bolts from loosening over time.
What liquids and chemicals are these M16 NBR washers resistant to?
NBR (Nitrile Rubber) offers excellent resistance to petroleum-based oils, mineral oils, hydraulic fluids, grease, water, and alcohols. However, it is not recommended for use with strong acids, ketones, or brake fluids.
