ViquaQS-001 UV Replacement Quartz Sleeve for the Viqua VH200 system

Q: Does this replace the glass tube on a pamapic 4200 btu pyramid propane heater?

I used it to replace the housing around our UV water treatment lamp. I’m sorry- I don’t know if it would work for that.

Q: Will this work with a gds-8 model system?

Not sure, but input your model into Amazon search and you will find it. https://www.amazon.com/LSE-Lighting-Treatment-Services-GDS-12/dp/B075JXC5HD/ref=mp_s_a_1_1?crid=2KO6OOA5OHSX3&keywords=gds-8+uv+light+replacement&qid=1669811688&sprefix=gds%2Caps%2C98&sr=8-1
