160mm Male Connector Galvanised Spiral Duct SPIRC160

160mm Male Connector Galvanised Spiral Duct SPIRC160

The SPIRC160 is a 160mm male connector (coupler) for galvanised spiral ducting, used to join two lengths of female-ended SPIR160 spiral tube together to extend a duct run. Manufactured from galvanised steel to DW144 specification, the connector slides into the female ends of adjoining duct lengths, where it is secured with self-drilling screws or rivets and sealed with tape or sealant for airtightness.

Joins
Male vs Female Connectors: The SPIRC160 (male connector) joins two female-ended duct lengths together. If you need to join two male-ended fittings (e.g. two bends), you will need a female connector instead — these are different parts and not interchangeable.
Key Features
Tube-to-Tube Joint
Specifically sized to join two lengths of 160mm female spiral duct — the most common joint type when extending a straight duct run beyond a single 3m section.
Galvanised Steel Construction
Manufactured from galvanised steel to DW144 specification, matching the corrosion resistance and durability of the SPIR160 duct tube.
Slip-Fit Installation
The connector body slides into the female socket of each duct length, providing a positive alignment before mechanical fixing — speeding up installation of long runs.
Secure with Screws or Rivets
Once positioned, the joint is secured using self-drilling screws or pop rivets through the overlap of the connector and duct wall.
Sealable for Airtightness
Apply aluminium foil tape or duct sealant around the joint after fixing to achieve higher airtightness classes (Class B/C/D to EN 12237) where required by the system design.
System-Wide Compatibility
Designed to work with the full 160mm galvanised spiral range — straight duct, bends, tees, and reducers — wherever a tube-to-tube extension is needed.

Use With SPIR160 — 160mm female-ended spiral duct lengths
Frequently Asked Questions
How many connectors do I need for a duct run?
Order one SPIRC160 for each joint between two straight duct lengths where the run extends beyond a single 3m section. Joints between duct and fittings (bends, tees) typically don't need a separate connector, as fittings are male and fit directly into the female duct end.
Do I need to seal the joint after fixing the connector?
For basic ventilation applications, mechanical fixing alone may be sufficient. For systems requiring a higher airtightness class (Class C or D to EN 12237) — common in MVHR and energy-efficient builds — seal the joint with aluminium foil tape or an approved duct sealant after fixing.
Can I use this connector with flexible ducting?
The SPIRC160 is designed for rigid spiral duct-to-duct joints. For connecting flexible duct to a rigid spiral system, the flexible hose is typically slid over the male spigot of a fitting or connector end and secured with a worm-drive clip (WDC160).
What's the difference between a male and female connector?
A male connector (SPIRC160) is sized to insert into two female duct ends. A female connector is sized to receive the male spigots of two fittings (e.g. joining two bends together). Check which ends you are joining before ordering.
