FAQ

Should I buy a kit or one exact size?

Buy one exact size when ID x CS is known. Choose a kit when you need to compare nearby sizes or keep backup repair stock.

Are these equipment-specific kits?

No. They are general repair and trial fitting kits. Check original dimensions and material requirements before ordering.

What if I need a custom material or 100+ pcs?

Use Bulk Quote for custom, high-volume, drawing-based, or special material requests.
