Agena offers the largest selection of after-market end caps and dust plugs in the astronomy industry. Available in dozens of sizes and in a choice of materials and colors, we just might have that hard-to-find end cap to replace the one you lost (or never had) for your eyepieces, binoculars, accessories, etc.
These vinyl caps are extremely flexible and durable protective closures. While primarily used in industrial applications, they work remarkably well as dust and moisture seals for your astronomy accessories too. Their bright yellow color makes them easy to find if you drop them in the dark. Please note that these caps have a nipple in the center on the outside, so it can be hard to stand your eyepieces on end if you use these caps on the bottom. Sold individually.
Useful Resources
A = 50.8mm / 2"
B = 54.4mm / 2.14"
C = 12.7mm / 0.5" (approx.)
Internal Ridges = No
Imprint inside cap = None
Notes:
(1) Some, but not all, end caps have 6-8 ridges on the inside rim. If these are present, the end cap size (A) is measured between diametrically opposite ridges as this will be the smallest internal dimension.
(2) If no ridges are present, (D) will be the same as (A). If ridges are present, (D) is typically 0.5-1mm larger than (A).
(3) The inside depth of the end cap is typically 1-2mm smaller than dimension (C).
(4) Dimensions (B) and (C) are subject to change without notice.
