these come in a 10-pack right? just want to make sure before i order, got a few machines that need new seals
Question by: Janet B on Sep 3, 2025, 4:17 PM
packaged in quantities of 10. The inside diameter runs 4.109 inches actual, outside diameter is 4.387 inches actual, and the width comes in at 0.139 inches. If you've got multiple units needing the same seal, ordering one pack should cover a good chunk of that work.
Answer by: Customer Support on Sep 5, 2025, 6:14 AM
got an old seal marked -243. is this the same size or am i fixin to order the wrong one
Question by: Lance H on Dec 27, 2025, 2:30 PM
Match it up by dash size and dimensions. This one is dash size -243 with a nominal 4-1/8 inch ID, 4-3/8 inch OD, and 1/8 inch nominal width. The actual measurements are about 4.109 inch ID, 4.387 inch OD, and 0.139 inch width.
