Description
LICOTA Piston Ring Compressor, 4" Capacity 3-1/2" to 7" (90-175mm) — Made in Taiwan
An adjustable band-type piston ring compressor used to compress piston rings evenly during engine assembly, letting the piston slide into the cylinder bore without snagging or breaking a ring.
Specifications:
- Capacity: 3-1/2" to 7" (90–175mm)
- Band width: 4"
- Origin: Taiwan
Why it works for you: Even ring compression prevents cracked rings and scored cylinder walls during piston installation — a must for engine rebuild work.
