Hi guys, I'm trying to find out if anyone knows where i can get CO2 resistant pipe for my diffuser around Durban?
Try, pneumatic stores near you. Ask for polyurethane 4/6mm ID/OD (inner diamenter of 4mm and outer diameter of 6mm) tubing. It's generally in the region of R25- R30 per meter for black or clear. If you don't come right that side, I can post some to you. I prefer clear (at least from bubble counter or check valve to diffuser), as this allows one to quickly catch water creepage or siphoning if check valve fails. Something you wont notice if using a solid colour PU tubing until too late.
