Component Types We Manufacture
Rubber Components for EV Charging Infrastructure
EV charging stations — whether Level 2 AC wall-mounted units, DC fast chargers, or public charging hubs — operate in harsh outdoor environments and require robust sealing, flame protection, and ingress protection to ensure safe, reliable operation over their 10-15 year service life. ARPL manufactures a comprehensive range of custom molded rubber components for EV charging station OEMs and EVSE (Electric Vehicle Supply Equipment) manufacturers across India and global markets.

Materials for EV Charging Station Components
Selecting the right elastomer for EV charging station components requires balancing flame retardancy, weather resistance, IP rating performance, and service temperature range. Our material engineers help EVSE manufacturers choose the optimal compound for each sealing application.
Material Options
| Material | Temperature Range | Key Properties | Typical Applications |
|---|---|---|---|
| FR Silicone | -60°C to +200°C | UL 94 V-0, excellent UV/ozone resistance, low compression set | Enclosure gaskets, display seals, EMI gaskets for outdoor chargers |
| Silicone Sponge (Closed Cell) | -60°C to +200°C | UL 94 V-0, excellent compression, lightweight, low closure force | Service panel gaskets, door seals, maintenance access panels |
| EPDM | -50°C to +150°C | Excellent weather, UV and ozone resistance, cost-effective | Cable grommets, outdoor enclosure seals, weather strips |
| Neoprene (CR) | -40°C to +120°C | Good flame resistance, moderate oil resistance, weather resistant | Cable boots, strain reliefs, connector covers |
| Solid Silicone (HCR/LSR) | -60°C to +200°C | Biocompatible, high transparency options, extreme temp range | Charging gun covers, dust caps, precision-molded seals |
| Conductive Silicone | -55°C to +200°C | EMI shielding up to 120 dB, nickel/silver filled, UL 94 V-0 | EMI gaskets around inverters, displays, communication modules |
Critical Design Factors
- UL 2202 compliance — gaskets must support overall charger certification to UL 2202 / IEC 61851 standards
- IP rating validation — gasket geometry, compression ratio, and material hardness must be optimized for target IP54/IP65/IP67
- Flame retardancy — UL 94 V-0 or V-1 rating mandatory for components near electrical connections
- UV and ozone resistance — outdoor chargers face 10+ years of UV exposure, requiring stabilized compounds
- Compression set resistance — service panel gaskets must maintain seal after repeated opening/closing cycles
- Operating temperature — charger electronics generate heat, requiring gaskets stable from -40°C to +85°C minimum
EV Charging Station Component Applications
AC Charging Stations (Level 2 Wall Box)
Level 2 AC chargers (3.3 kW to 22 kW) are the most widely deployed EV charging solution for homes, offices, and commercial parking. These wall-mounted or pedestal-mounted units require compact enclosure gaskets, cable entry grommets, and display panel seals that maintain IP54/IP65 protection in outdoor installations. ARPL supplies FR silicone gaskets and EPDM grommets to EVSE manufacturers for Tata Power, Ather Energy, ChargeZone, and other Indian charging network operators.
DC Fast Chargers (50 kW to 350 kW)
DC fast chargers handle high power levels and generate significant heat, requiring robust thermal management and enhanced sealing. Enclosure gaskets must seal larger cabinets housing power electronics, cooling systems, and payment terminals while meeting UL 2202 and IEC 61851 safety standards. Charging gun rubber covers for CCS2 and CHAdeMO connectors protect high-current DC pins from moisture and contamination. Cable boots and strain reliefs protect heavy-gauge charging cables at their termination points.
Charging Gun Covers & Port Caps
Rubber dust caps and protective covers for EV charging connectors are critical for maintaining contact integrity and preventing corrosion. ARPL manufactures custom molded covers for Type 2 (IEC 62196-2), CCS2 (IEC 62196-3), CHAdeMO, and GB/T connector standards. These covers are molded in UV-stabilized EPDM or silicone rubber and designed for 10,000+ insertion cycles. Vehicle-side charging port inlet caps protect the socket when not charging, preventing water and debris ingress into high-voltage contacts.
Public Charging Hubs & Highway Stations
Large-scale public charging installations at highways, fuel stations, and commercial hubs require ruggedized rubber components that withstand extreme weather, vandalism, and continuous heavy use. ARPL supplies high-durometer enclosure gaskets, reinforced cable boots, and impact-resistant grommets for charging stations deployed by NTPC, BPCL, HPCL, and Tata Power across Indian highways. All components meet IP67 and IEC 60529 ingress protection requirements for outdoor installations.
Global Export Markets
ARPL supplies EV charging station rubber components from India to EVSE manufacturers and charging network operators in USA, Germany, Netherlands, South Korea, Japan, the UAE, and Brazil. Our components support CCS1, CCS2, CHAdeMO, GB/T, and NACS connector standards used across global markets.

Frequently Asked Questions
Common questions about EV charging station rubber components
EV charging stations use enclosure gaskets (IP65/IP67 rated), charging gun rubber covers and dust caps, cable entry grommets, cable boots and strain reliefs, display panel gaskets, service door seals, EMI shielding gaskets, and flame retardant seals. These components protect sensitive electronics from rain, dust, UV, vibration, and electromagnetic interference while meeting UL 2202 and IEC 61851 safety standards.
Outdoor EV charging stations typically require IP54 to IP67 rated gaskets. IP54 protects against splashing water from any direction, while IP67 provides complete dust-tight sealing and protection against temporary water immersion up to 1 metre depth. The required IP rating depends on the charger's installation location, mounting orientation, and the specific compartment being sealed.
FR (flame retardant) silicone and closed-cell silicone sponge are the preferred materials for EV charger gaskets due to their UL 94 V-0 flame rating, wide temperature range (-60°C to +200°C), UV resistance, and excellent compression set properties. EPDM is used for outdoor weather sealing and cable grommets. Neoprene offers good flame resistance at lower cost. Conductive silicone is used for EMI shielding gaskets around sensitive electronics.
ARPL manufactures rubber dust caps and protective covers for all major EV charging connector standards — Type 2 (IEC 62196-2), CCS2 (IEC 62196-3), CHAdeMO, and GB/T. These covers protect charging pins from dust, moisture, and UV degradation when not in use. They are molded in UV-stabilized EPDM or silicone rubber and designed for 10,000+ insertion cycles with integrated tethering features.
UL 2202 is the Standard for Electric Vehicle Charging System Equipment, referencing UL 50 (enclosures), UL 50E (environmental enclosures), UL 94 (flammability), UL 508 (industrial control equipment), and UL 746C (polymeric materials). Gaskets used in UL 2202 compliant chargers must meet UL 94 V-0 or V-1 flame ratings, demonstrate adequate compression set resistance, and maintain their sealing properties over the charger's rated service life.
