Frequently Asked Questions
Q: What is the application of the HY 39382 o-ring on Hyster equipment?
A: The HY 39382 is an OEM o-ring seal for Hyster electric lift trucks and electric pallet jacks. It seals hydraulic cylinders, valve bodies, pump connections, and control component assemblies. This part prevents hydraulic fluid leakage in pressurized systems.
Q: How does the HY 39382 differ from the HY 39381 o-ring?
A: Both are Hyster OEM o-rings but are sized differently for specific equipment locations. The HY 39381 and HY 39382 have different inside diameters, outside diameters, or thicknesses. Use the correct part number for your application. Installing the wrong size will result in leakage or seal failure.
Q: What fluid types is the HY 39382 o-ring compatible with?
A: The HY 39382 is compatible with mineral-based hydraulic fluids (ISO VG 32 through VG 68) specified for Hyster electric trucks. Fluorocarbon (FKM) o-rings tolerate synthetic fluids and biodegradable ester oils. NBR (nitrile) o-rings do not resist synthetic fluids. Confirm material type of your HY 39382 before switching hydraulic fluid brands or types.
Q: Can the HY 39382 be used as a field repair seal for multiple truck brands?
A: The HY 39382 is designed for Hyster equipment. It can substitute on Crown, Toyota, Raymond, Yale, or other brands only if dimensions match exactly. Measure o-ring groove width and depth on the non-Hyster truck before ordering. Dimension mismatches will cause seal failure and hydraulic leakage.
Q: How should the HY 39382 o-ring be stored before use?
A: Store the HY 39382 in a cool, dry environment away from direct sunlight, ozone, and heat sources. Keep o-rings in original packaging. Avoid contact with oils, greases, or solvents other than the hydraulic fluid they will be exposed to in service. Improper storage degrades elastomer material and reduces seal life.
