Frequently Asked Questions
What is an internal stop ring plier used for?
Internal stop ring pliers are used to compress internal snap rings or circlips so they can be placed/removed from a bore or housing. This straight-nose version is ideal for direct-access applications in marine machinery.
What is the difference between straight and angled internal ring pliers?
A straight-nose plier works best when the snap ring is unobstructed. Angled pliers are needed when the ring is in a recessed or offset position. This model is the standard choice for common marine equipment repair.
How do I maintain these pliers in a marine environment?
After each use, wipe the pliers dry. Apply a light coat of oil to the hinge and tips to prevent corrosion. The anti-corrosion finish provides basic protection, but regular maintenance ensures long service life.
What is the IMPA code for these pliers?
The IMPA code is 611821, which classifies these pliers as a hand tool for ship chandlery and marine supply purposes.
