Product Questions & Answers

These the right o-rings for the 4FI12 block coupler, or do I need to order something separate for the half-inch size?

Question by: Rick B on Aug 27, 2025, 11:36 AM

KIT 4FI12 OR is the correct o-ring kit for the 1/2 inch block coupler in that Faster lineup. The part is sized specifically for that coupler, so you won't need anything additional to get a proper seal on that connection.
