The PERRIN coupler is a 2.25" to 2.75" inside-diameter silicone joiner that is 4" long and finished in black with a PERRIN logo. It serves to connect differing pipe diameters in intake or coolant plumbing where a stepped silicone coupler is required. The compact, branded coupler simplifies transitions between adjacent tubing sizes in custom or stock plumbing runs.
