⚠️ IMPORTANT: BUYER'S GUIDE (SCANIA SEAT DIAGNOSTICS)
IDENTIFICATION: Please check the 1388227 number on your original distributor. This part is distinct due to its 3 vertical white plug interfaces.
FAILURE SIGNS: If your seat height or lumbar adjustment fails to hold air, or if you hear a hissing sound from the side of the seat, this distributor's O-rings or plastic body may be compromised.
REPAIR VS REPLACE: Replacing this connector head is the most cost-effective way to fix leaks without buying a complete (and expensive) seat valve assembly.
INSTALLATION TIP: Lightly lubricate the O-rings with silicone grease before insertion to ensure a perfect seal and prevent tearing during installation.
