Schrader Valve Adapter
[828-Schrader]

I bought 5 of these. Couldn't get them to seal on my Sea Anchor lanterns using Teflon tape. After disassembling I found excessive flashing on the inside of the cap, after removing this I greased a Brightlyt fuel filler cap viton washer and stuffed it in the cap and reassembled it. Worked like a charm on all 5. I used a Britelyte washer because the Sea Anchor washers were to thin to contact the pump barrel. All is well. I would buy again as there was a 7 dollar savings per valve....
