Question 1: What bottles do these caps work with?

Answer 2: No tools are needed. The fine side-thread design makes it easy to screw on and remove by hand, so you can swap caps quickly at home, at camp, or on the go.

Frequently Asked Questions
Find quick answers to the most common questions about our product.
Yes. ProSeal caps are designed with a precision thread and sealed silicone structure to help create a tight, dependable seal on compatible 1LB propane bottles. They’re made to replace flimsy caps that crack or loosen over time.
No tools needed. The side-thread design makes it easy to twist the caps on and off by hand, which is ideal for camping, storage, and quick bottle changes.
Brass offers much better durability than the plastic caps that usually come with small propane bottles. It resists wear, holds threads better, and gives you a more secure long-term seal.
ProSeal is made for many standard 1LB refillable propane bottles and compatible portable heater setups. It also works with select Coleman, GoodCamp, Mr. Heater Big Buddy, and Fuel Keg bottles.
