Vectra Coupling Kit
Gen 2 Vectra pumps take standard PVC pipe sizes, and this is the coupler that makes it possible. EcoTech Marine's Gen 2 QuickCouple coupling kit connects the Vectra volute to your tank's plumbing, sold per model size as the S2, M2 or L2 kit. Unlike the first-generation coupler, the Gen 2 design accepts standard PVC pipe directly through EcoTech's "Easy Turn Grips", and it's the part most owners eventually replace after the original cracks or is lost during a service.
Key features
- Genuine EcoTech part – the collar and coupling assembly EcoTech supplies for Gen 2 Vectra volutes.
- Standard PVC-size fittings – Gen 2's redesigned coupler accepts common PVC pipe sizes directly, unlike the proprietary Gen 1 fitting.
- Sold per model size – order the kit matching your S2, M2 or L2 pump.
- Tool-free fit – EcoTech's QuickCouple hand-tightened connector system.

Which one do I need?
Match the kit to your pump size and generation, not just your plumbing diameter. This is the Gen 2 kit – it will not fit a Gen 1 Vectra S1, M1 or L1 volute, which uses a different, proprietary coupler thread. If your pump is an S1, M1 or L1, you need the separate Gen 1 collar and coupling kit instead.
Suitable for, and not suitable for
Suitable for Gen 2 Vectra S2, M2 or L2 owners replacing a worn, cracked or missing coupler, or reconfiguring plumbing to standard PVC sizes. Not suitable for Gen 1 Vectra S1, M1 or L1 pumps.
What's included
The collar and coupling hardware for one pump, matched to the variant ordered. EcoTech does not publish an itemised contents list beyond the collar and coupling assembly – plumbing pipe and the pump itself are not included.
Care and maintenance
When should I replace it?
Whenever the existing coupler is cracked, has lost its seal, or is missing after a service. EcoTech doesn't publish a fixed replacement interval – check it whenever the volute is apart for an impeller clean.
Goes well with
- The matching Vectra impeller for your pump size, if servicing the pump at the same time.
- A Vectra cable extension, if repositioning the pump further from its controller.
Warranty and delivery
Covered by EcoTech's standard 12-month manufacturer warranty from date of purchase, in addition to your rights under Australian Consumer Law. Standard delivery Australia-wide.
Common questions
Can I use this on my old Vectra M1?
No. The Gen 2 coupler thread is different from Gen 1 – this kit only fits the Vectra M2 volute, not the M1.
Does this let me plumb in standard PVC pipe?
Yes – Gen 2's coupler was redesigned around standard PVC pipe sizes, which is one of the main upgrades over the original Vectra coupler.
Do I need tools to fit it?
No – it uses EcoTech's tool-free, hand-tightened QuickCouple system.
