Description
The 8mm Rigid Joiner provides a simple way to connect two compatible 8mm push-in fittings directly together. Made from rigid polypropylene, it measures 6mm ID × 8mm OD × 50mm long.
Instead of placing flexible line between two fittings, the rigid joiner creates a short and tidy straight connection. Therefore, it is particularly useful when building compact Duotight kegging and dispensing systems.
Duotight Compatible 8mm Connection
The joiner has an 8mm (5/16″) outside diameter, allowing each end to push directly into compatible 8mm Duotight fittings.
Because the joiner is rigid, it helps keep closely positioned fittings aligned. As a result, you can create a cleaner installation where a short section of flexible tubing would be unnecessary.
Connect Duotight Inline Regulators
One particularly useful application is connecting multiple Duotight 8mm Inline Regulators with Gauge.
The rigid joiner allows compatible inline regulators to connect directly together. Therefore, you can use several regulators to create a compact multi-pressure gas manifold.
For example, a single main CO2 supply can feed several inline regulators. Each regulator can then reduce the pressure independently for different kegs or dispensing requirements.
Useful Throughout Duotight Systems
The 8mm Rigid Joiner can also connect other compatible 8mm push-in fittings where you need a short, straight and rigid connection.
Typical uses include:
- Connecting compatible Duotight fittings
- Joining Duotight inline regulators
- Building compact gas manifolds
- Creating short straight connections between fittings
- Reducing unnecessary flexible tubing between nearby fittings
- Keeping closely mounted fittings neatly aligned
Because both ends have an 8mm OD, installation is straightforward. Simply push each end fully into the compatible push-in fitting.
