Can this be clamped, or does it need to be crimped?

Good afternoon, Our barb fittings can be either crimped or clamped. It all depends on what tool you have and which ring you prefer.

The Poly Alloy connections - Are they Alloy with a Poly coating? Trying to determine if they could be used with salt water aquariums and not leach anything including copper into the water - same as PVC parts.

Asked by: MarkZ
Greetings MarkZ, All our fitting are only certified and suggest to be used with potable water. This product is made of Acrudel type material. We would not recommend using this with your aquarium.
