Check the listing for details. ONE (1) Coleman (Same As Part #216-5091) - Leather Pump Cup. Condition: New. Listed at 9.00 USD. 1 leather pump cup. This is the common size that fit the vast majority of Coleman products. The cup diameter is approximately 7/8" (also referred to as the 21mm size). This leather washer is made by me from high quality vegetable tanned leather -- vegetable tanned leather is safe for use with the metal in your stove/lantern. (Non-vegetable tanning processes have chrome alum/chromium salts in the leather which corrode metal over time). This leather cup is a perfect fit in your Coleman lantern or stove. It works in Coleman lanterns and camp stoves that are white gas / Coleman camp gas / naphtha / kerosene liquid fueled. I can send it pre-soaked in neatsfoot oil so you can use it immediately or I can it dry for longer term storage so it won't attract dust. **Just let me know how you want it (by default I will send it pre-soaked). I will email installation instructions (with photos) of how to install the leather pump cup with purchase. A Leather cup can be installed in just a few minutes with just common everyday household tools/items. Get rid of the neoprene cups! Upgrade to leather. At checkout, please indicate if you want them dry in the note to seller box - otherwise I will send them pre-soaked (the default).
