RUKO ENR-RU-25.0mm EPDM Rubber End Cap, Black, 25.0 mm ID, 28.0 mm OD, 25.0 mm Length

In industrial control panels and electrical enclosures, open cable ends are exposed to moisture, dust, and accidental contact. The RUKO ENR-RU-25.0mm end cap seals those ends, protecting conductors and maintaining insulation integrity. Made from black EPDM rubber, it slips over cable or conduit ends with a 25.0 mm inner diameter and stays secure with a push-on fit.

Why choose it

EPDM rubber offers long-term elasticity and resistance to environmental stress, so the cap stays in place and protects against moisture ingress and mechanical damage. Its push-on design requires no tools or adhesives, speeding up installation in production or field service.

Ideal use cases

• Sealing unused cable ends in control cabinets
• Protecting conduit openings during transport and storage
• Insulating wire ends in automotive and industrial wiring harnesses
• Preventing contamination in pneumatic or hydraulic line ends

Good to know

The cap is halogen-free and RoHS compliant, making it suitable for applications with strict environmental requirements. Its flexibility allows it to fit slightly irregular or oval cable ends while maintaining a reliable seal.
