The Story

The Verplas VKC674 is a 150mm metal worm-drive hose clip designed for securing flexible duct hoses to rigid spigots in 150mm ventilation systems. It provides an adjustable, screw-tightened clamp that creates a secure, airtight connection between flexible PVC or aluminium flex hose and the male spigots of fans, connectors, grilles, bends, and T-pieces. Suitable for all domestic and commercial ventilation applications including whole-house MVHR, dMEV, and single-room extract systems.

When Worm Clips Are Required: Worm clips are essential when connecting flexible duct to any rigid spigot — fan units, rigid fittings, grilles, and dampers. The clip prevents the hose from slipping off under system pressure or vibration and improves joint airtightness.
Key Features
Worm-Drive Screw Mechanism
The screw-driven band tightens evenly around the hose, compressing it firmly onto the spigot to create a secure, airtight connection that resists both pull-off and vibration loosening.
Adjustable Fit
The worm-drive adjustment accommodates minor variation in hose wall thickness and spigot diameter, ensuring a tight fit across different flexible hose types.
Metal Construction
Steel band and screw housing provides durability and long service life in the damp, variable-temperature conditions of loft and ceiling void installations.
150mm Nominal Size
Sized for use with 150mm flexible duct hoses (VFD6/3 PVC flex and VFD6/10INS insulated hose) on 150mm male spigots.
Fast Installation
The clip is pre-assembled and ready to use — slide over the hose, position over the spigot, and tighten with a screwdriver or nut driver in seconds.
Multi-System Use
Suitable for MVHR, dMEV, single-fan extract, passive stack, air conditioning, and HVAC systems wherever 150mm flexible hose is used.

Frequently Asked Questions
How tight should I tighten the worm clip?
Tighten until the hose is firmly compressed onto the spigot without the band cutting into the hose material. Finger-tight plus 1–2 turns with a screwdriver is typically sufficient for PVC flex.
Do I need one clip or two per connection?
One clip is standard for each hose end. For higher-spec or pressurised systems, two clips per connection (one at each end of the overlap) can improve airtightness.
Can I reuse worm clips?
Yes — worm clips are fully reusable. Loosen the screw to release the hose, and re-tighten on a new connection when required.
Are these clips stainless steel?
The VKC674 uses standard steel. For coastal or highly humid environments where corrosion resistance is required, specify a stainless steel worm clip.
