The unique design of the Lang Tools Universal Seal Puller Kit, No. 850, allows the user to have various angles and leverage points to engage and remove a seal. The jaw width will engage a larger surface area than the competition, says the company, which will prevent the tearing of the seal and reduce the frustration of the user. Each puller head will work with any 3/8” drive ratchet or breaker bar and the two leverage pin lengths will allow use on various diameter seals. This product is proudly designed, engineered, and made in the U.S.A. The convenient 4-pc kit includes a large pivot pin, a small pivot pin, large seal puller head and small seal puller head.
