Our Product Range of Extruded Rubber Seal Strips
EPDM Weather-Resistant Rubber Seal Strip
EPDM ranks as our most popular outdoor sealing material. It features excellent UV, rainwater, and aging resistance, along with good elasticity and compression resistance.
For this reason, we use EPDM seal strips for truck door weatherstripping, construction window gap filling, and ship hatch waterproof sealing. It can effectively prevent water leakage, dust ingress, and aging failure caused by long-term sun and rain exposure.
Oil-Resistant NBR Nitrile Rubber Sealing Strip
NBR material delivers top-tier resistance against oil, wear, and tearing. Specifically, it works perfectly in spaces that touch mineral oil, diesel, gasoline, and lubricant oil.
We supply NBR seals for excavator cabin enclosures, hydraulic tank surrounding gaskets and kitchen mechanical oil contact parts. These strips maintain steady sealing performance and extend service life for industrial leak prevention.
High & Low Temp Resistant Silicone Rubber Seal Strip
Silicone rubber sealing strips offer excellent resistance to extreme temperatures, remaining stable from –60°C up to 250°C. They are eco-friendly, soft to the touch, and fully weatherproof.
These strips perform reliably across a wide range of applications, including household appliances, automotive engine compartments, and high-temperature industrial sealing systems.
Flame Retardant Neoprene Sponge Rubber Seal Strip
Neoprene (CR) sponge sealing strips feature reliable flame retardancy. Besides, they absorb vibration, muffle noise, and stand up to chemical corrosion.
Thanks to their porous sponge structure, these strips offer great compression rebound and air tightness.
For industrial use cases, we fit these seals into fireproof equipment, electrical cabinets, and all shock & sound insulation assemblies. They efficiently isolate vibration, cut down noise, and shield parts from outside corrosive fumes.
Other Optional Raw Materials for Custom Sealing Strips
Co-Extruded Rubber Sealing Strip Solutions
Dual Durometer Sponge and Solid Rubber Extrusions
Dual durometer co-extruded rubber seal integrates solid rubber and sponge rubber into one piece through one-time co-extrusion molding.
The solid part provides strong support and fixing performance. On the other hand, the sponge part adds elasticity and tight sealing. It has excellent compression resilience and air tightness. We widely apply this design for car doors, windows, container hatches, and other airtight sealing scenes.
Extruded Rubber Profiles With Metal Insert
Metal insert co-extruded rubber sealing strip is compounded with galvanized steel sheet or aluminum sheet inside the rubber body. The metal framework enhances the overall structural stability and shape retention of the sealing strip, avoiding deformation and falling off after long-term use.
These Composite steel-reinforced rubber sealing strips combine the advantages of metal and rubber, ensuring superior sealing performance and service life.
Co-extrusion rubber seal profiles are widely applied across multiple industries, including transportation, automotive (as auto rubber seal strips), industrial equipment, and construction doors & windows.

FAQ For RNTICO Rubber Sealing Strips
Rubber sealing strips are flexible strip-style sealing parts. We produce them mainly from rubber via extrusion and compression molding. They fill gaps with elastic deformation to reach waterproof, dustproof, sound insulation, and shock absorption effects.
We offer EPDM, Nitrile, Silicone, Neoprene, NR, FKM, PVC, TPE, TPV, etc., to meet different working conditions.
As a key sealing component, rubber sealing strips not only extend the service life of equipment and structures but also significantly improve product performance, safety, and user experience.
Yes, we support solid, foam, hollow, special-shaped cross-sections and tailor-made sizes based on your 2D/3D drawings or samples.
Lead time varies by size, cross-section complexity, and quantity. Reach out for specific details.
Choose materials based on your working conditions (weather/oil/temp resistance), material traits (EPDM, NBR, silicone), technical specs, and budget. Our team can help you pick the best fit.
Solid sealing strips are dense, wear & pressure resistant for tight heavy-duty sealing. Foam sealing strips are soft, elastic, with great sound/heat insulation, fit low-pressure filling scenarios.
