View Full Version : Polyamide 6 - safe for reef tank?

07/17/2017, 05:19 AM
Hi I need a 'tee' hose reducer to run a reactor and wondered if this is a safe material?

"Polyamide 6, 30% Glass Fiber Reinforced"

Item: http://www.ebay.co.uk/itm/291848705304

All I could find is this old thread, is the information still accurate?

Is there a better material I should look for?

I need to go from 16mm ID to 10mm ID, and I can't seem to find an aquarium manufacturer selling 'tee' pieces in that size.

Many thanks

I'd be cautious about trusting it with saltwater. Products rated for drinking water might be fine over the long haul. I'd start looking there.

Many thanks Bertoni, any idea on materials which would be safe?

I've looked through what seems like hundreds of listings and not found what I need so any keywords I can narrow down the search with would really help!

yes nylon/poly6 is totally fine to use in a tank..

most if not all plastics are totally fine/inert..

It was just the comment in the linked thread that nylon 6 becomes brittle that concerned me.

Nylon 6 can become brittle but only when its dried out or in a low humidity environment and its moisture content is very low..
Salt ions can cause it to become more brittle vs "non-salt" water exposure but again thats only once its lost its absorbed moisture..

With continuous exposure to moisture/humidity it shouldn't have any issues and is used in many marine applications..
