Question by: Chad B on Mar 7, 2026, 9:44 AM

trying to match up parts here, is the 20SFO the -20 code 61 split flange kit with the 2 inch flange head?

Answer by: Customer Support on Mar 8, 2026, 1:07 PM

It is a Code 61 split flange kit for dash size -20 with a 2.00 inch flange head diameter.

Question by: Pete H on Oct 9, 2025, 7:23 PM

what's the torque spec on the bolts for this split flange kit? want to make sure we're not over or under tightening when we put it together

Answer by: Customer Support on Oct 11, 2025, 6:50 AM

Bolt torque on this kit runs between 425 and 550 lb-in for the grade 8 hex bolts included. Stay within that range and you'll get a proper seal without risking damage to the flange halves or the O-ring. The four lock washers in the kit help keep things from backing off once torqued down.

Question by: Darryl S on Aug 10, 2025, 4:48 PM

i’ve got a -20 flange head setup, is this the right split flange kit size for that?

Answer by: Customer Support on Aug 12, 2025, 8:46 AM

The key callout is the dash size and flange head diameter. This kit is a -20 (2.00 inch) Code 61 split flange kit, and it comes with the matching 90 durometer Buna-N O-ring plus the bolts and lock washers.
