Replacement Fuel Bottle Cap

In 1969, Seattle engineer and lifelong mountaineer Larry Penberthy established Mountain Safety Research as a one-man crusade dedicated to improving the safety of climbing equipment. The driving force behind Larry's passionate endeavor was a simple belief that still motivates our team today: the idea that better, safer, and more reliable equipment is the key to unlocking greater adventures.

Designing for Durability and Longevity is at the core of our approach. We build products to last, offering outdoor enthusiasts more adventures and reducing the amount of goods piling up in landfills. Our first priority is to design and manufacture durable, long-lasting products. Extensive testing, both in-house and in the field, allows us to ensure that our products will stand up to the wear and tear to which our customers subject their gear.

Our products have stood the test of time, and we often hear stories from customers who are still using MSR stoves from the 1980s. We believe in what we make and stand behind it.

The Classic replacement cap for all MSR Fuel Bottles is a testament to our commitment to durability and longevity. Weighing only 0.4 oz (11 g) and measuring 1.8 x 1.4 x 1.5 in (4.6 x 3.6 x 3.8 cm), this cap is made in the USA and is designed to provide reliable performance for years to come.

At the heart of our brand is the belief that better, safer, and more reliable equipment is the key to unlocking greater adventures. This principle has driven us since our inception and continues to guide our design and manufacturing processes today. By creating products that are built to last, we aim to empower outdoor enthusiasts to push the boundaries of their experiences, all while reducing the environmental impact of their gear.
