Product Overview

The EPDM Rubber Gasket & Anti-Vibration Cushion Strip is an indispensable component engineered specifically for ductile iron and cast iron manhole cover assemblies. Inserted securely into the precision-machined groove of the manhole frame, this elastomeric gasket serves as a durable buffer. It effectively cushions heavy traffic loads, seals out unwanted environmental factors, and eliminates the common issue of metallic noise disruption in urban areas.

Key Features & Advantages

Exceptional Noise Damping & Vibration Control: When heavy vehicles pass over the manhole cover, our EPDM strip absorbs the massive structural impact, eliminating harsh metal-on-metal clanging noises and creating a quieter urban traffic environment.
Superior EPDM Material Performance: Manufactured from premium-grade vulcanized EPDM rubber. It offers outstanding resistance to ozone, UV radiation, extreme temperatures (-40°C to +120°C), and harsh outdoor weather, ensuring it won't crack or degrade underground.
Extended Infrastructure Lifespan: By absorbing continuous traffic shocks, the rubber gasket minimizes mechanical wear and tear between the cover and the frame seat, significantly reducing maintenance costs and preventing premature frame fractures.
Excellent Sealing & Anti-Infiltration: Provides a reliable compression seal that prevents surface rainwater, silt, and debris from leaking into drainage networks, while keeping underground foul odors locked inside the sewer.

Customization & Engineering Capabilities

As an experienced manufacturer of municipal castings and accessories, we can customize the rubber strips to match your exact structural designs:

Custom Profiles: Available in continuous extrusion rolls or pre-joined continuous rings tailored to precise diameters (e.g., 600mm, 700mm, 800mm).
Hardness Optimization: Adjusted Shore A hardness according to the heavy-duty load requirements of your project (such as D400 or F900 airports/docks).
Drawing Matching: We can custom-die or extrude profiles exactly based on your provided CAD drawings or technical samples.

Why Source From Us?

One-Stop Sourcing: Easily bundle your ductile iron manhole covers, water meter boxes, and these matching EPDM gaskets in a single shipment to reduce logistics overhead.
Direct Factory Pricing: Cut out middleman costs with reliable bulk supply straight from our production line.
Strict Quality Control: Every batch undergoes rigorous compression, hardness, and elongation tests to guarantee long-term field stability.
