FAQ

Q1: How do I verify if this 20x31x7 oil seal fits my engine?
A1: Please measure your existing oil seal’s inner diameter (ID), outer diameter (OD), and thickness. This seal is designed for a 20mm ID, 31mm OD, and 7mm thickness. It is specifically intended for the Fuel Injection System of diesel engines. Cross-reference these dimensions with your application.

Q2: What is the recommended installation procedure for this seal?
A2: Ensure the housing bore and shaft are clean and free of burrs. Lubricate the seal lip with clean engine oil before installation. Use a proper seal driver or socket that matches the outer diameter of the seal to press it evenly into the housing. Avoid using a hammer directly on the seal to prevent deformation.

Q3: What is the minimum order quantity (MOQ) and how is the product packaged?
A3: The minimum order quantity is 500 pieces. Standard packaging is neutral packing, with each single item weighing approximately 0.035 kg. For larger wholesale orders, we can discuss custom packaging options to suit your distribution needs.
