Complete Conduit Systems Designed for Installation Efficiency

Heyco’s comprehensive portfolio of liquid tight flexible conduit, tubing, and fittings are engineered for rapid assembly with no threading required.
Quick-twist and push-to-connect fittings eliminate conduit preparation and cutting risks to reduce installation time and labor costs. Each system provides IP-rated environmental sealing that protects electrical infrastructure in wet locations, outdoor environments, and industrial settings where moisture ingress can threaten system performance.

Key features of Heyco liquid tight flexible conduit systems:

• US-made for fast delivery
• IP67/IP68 rated options for dust and liquid tight protection
• Meets NEMA 3R, 4, and 4X standards
• UL and CSA approved for hazardous locations
• UV resistant for outdoor installations
• Available in NPT, PG, and Metric thread configurations
• Wide range of conduit sizes and flexible bend radii
• Quick-install fittings with no threading or special tools

Why Heyco Conduit Systems Outperform Standard Alternatives

Installation speed and efficiency make Heyco liquid tight conduit superior to traditional threaded systems. Quick-twist and push-connect fittings install without cutting threads into the conduit – eliminating the risk of compromised sealing that occurs when installers nick or damage the conduit wall during preparation.
Convex ferrules and silicon sealing glands create liquid tight connections without O-rings in many configurations. The conduit pushes onto the fitting ferrule and locks into place with a simple twist or compression nut – delivering NEMA-rated sealing in seconds instead of minutes.
And with Heyco’s broad size range across multiple material families, electrical contractors can standardize on one manufacturer across different projects – reducing inventory complexity and gaining consistent installation procedures.
