Fantasea Hybrid Vacuum Safety System M16A

The Hybrid Vacuum Safety System M16A is an optional pre-dive vacuum test and leak detector safety system. The system allows confirming the watertight seal of the housing prior to the dive using the vacuum system and monitoring the housing seal during the dive using the moisture detector. 


The Hybrid Vacuum Safety System M16A requires self installation. It can be installed and used inside the following housings: 

  • Fantasea housings equipped with an M16 port*. 
  • Other brands housings equipped with an M16 port, as long as the following requirements are met: 
    - Housing’s M16 port features a thread type that is compatible with the thread type featured on the vacuum valve of the Hybrid Vacuum Safety System M16A.
    - Housing consists of sufficient internal space to accommodate all vacuum safety system components in a manner that does not interfere with housing operation and allows operating the vacuum safety system. Please refer to the Features & Specifications section for components dimensions. 
    - Housing features a transparent area through which the LED indicator of the vacuum safety system can be observed and monitored. 

* Fantasea FA6500 Housings labeled with a serial number within the range of 187402 – 187617 require installing the Fantasea M16 Coarse to Fine Thread Insert Converter on the housing’s M16 port in order to accommodate the Hybrid Vacuum Safety System M16A.

April/May 2022 Delays:

Due to further Omicron outbreaks in China, some products may be delayed. Not all brands or products will be affected by this. As some products are kept in stock as a matter of course, these should not be affected.

If you need things urgently please contact us and check ETA on the items you require.

International Shipping

At the moment, our website is only set up to ship within New Zealand. If you live outside New Zealand, please contact us and tell us your full shipping address and what you want to purchase. Please note that our free shipping offer applies to NZ shipping only. Our preferred method of shipping internationally is DHL.

How long will it take for my order to arrive after I make payment?

That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

If we have it in stock, we can usually send it out as soon as we receive payment, or you can pick it up. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.

How do you ship my NZ orders?

We use New Zealand Post and CourierPost to ship orders. Our default is courier, though you may organise an alternative with us by contacting us directly. CourierPost aims for next day delivery nationwide between major towns and cities in the North Island. South Island delivery can take two days. If you require next-day delivery in South Island, choose the express shipping option for the South Island. If you spend over $250 get your shipping for free!

When you buy something from us, the price is literally exactly what it says on the tin.

If you buy something from an overseas supplier, that is most definitely not the case. While the product might seem like a great deal on screen, it's important to understand customs and import costs.

In addition to the ticket price on an overseas purchase, whatever the exchange rate is on the day (this can fluctuate wildly - trust us, we know), there are also tariffs, GST and border processing fees. This can easily add upwards of 25% to the ticket price. Items costing over NZ$1000 also incur import entry transaction fees.

In addition to these extra costs, Customs clearance can also cause delays. Sea Tech has been importing for years - we've got this down to a fine art, and we've built relationships with customs that help our items clear quickly.

By buying from Sea Tech, you avoid all the headaches, delays and extra costs. We handle all this stuff for you, so you don't even have to think about it.

These Nauticam housings are non-returnable, non-refundable, non-cancellable, and may be subject to extended lead times as they are manufactured on demand. We always do our best to meet trip deadlines so please advise us if you have a trip coming up!
