got a groove that takes a -214, is this the right quattro ring size and how many come in the pack
Answer by: Customer Support on Sep 14, 2025, 10:29 AM
The key identifier here is the dash size, and this one is a -214. Each package includes 5 Style QR Buna-N Quattro Rings.
Question by: Dean H on Dec 11, 2025, 8:19 PM
These the same as regular O-rings or is there somethin different about how they seal?
Answer by: Customer Support on Dec 13, 2025, 11:43 AM
Quad rings have a four-lobed cross-section instead of the round profile you get with a standard O-ring. That shape gives you two sealing contact points on each side, which helps cut down on spiral twist and rolling during movement. For dynamic applications especially, that added stability makes a real difference in how long the seal holds up.
