Parker Vibra-Lok Compression Fitting Sleeve 3/8 Inch Buna-N or Viton

Parker Vibra-Lok Compression Fitting Sleeve 3/8 Inch Buna-N or Viton

Keep your oil and fuel line connections sealed even when your engine shakes them apart. Parker Vibra-Lok replacement sleeves are the key component that makes these fittings vibration-proof – the sleeve cushions the tubing and allows it to flex inside the fitting, eliminating the micro-leaks that metal-on-metal compression fittings develop over time.

Key Features

• Available in Buna-N (green) for standard petroleum fluids or Viton (red) for high-heat and chemical-resistant applications
• Replacement sleeves extend fitting service life without replacing the entire fitting assembly
• Compatible with all Parker Vibra-Lok compression fittings using 3/8-inch OD tubing
• Sold individually – order one sleeve per fitting port that needs replacement

Technical Specifications

• Tubing OD Compatibility: 3/8 inch
• Buna-N (60VL-6): Green color – for petroleum-based oils, fuels, and lubricants
• Viton (60VLV-6): Red color – for high-heat and chemically aggressive fluid applications

Fitment Notes

• Fits all Parker Vibra-Lok compression fittings designed for 3/8-inch OD tubing
• Select Buna-N for standard engine oil, fuel, and coolant – select Viton if operating temperatures are elevated or fluid compatibility is a concern
• Inspect sleeves periodically and replace at first sign of deterioration to maintain a leak-free seal
