Parker Vibra-Lok Compression Coupling Union Fitting Brass 3/8 Inch x 3/8 Inch

Parker Vibra-Lok Compression Coupling Union Fitting Brass 3/8 Inch x 3/8 Inch

Join two 3/8-inch oil or fuel lines without worrying about vibration working the connection loose. Parker Vibra-Lok coupling unions use an elastomeric sleeve on each end to cushion the tubing and maintain a positive seal under the constant vibration, mechanical shock, and tube movement present on running motorcycles.

Key Features

• Joins two 3/8-inch OD tubes inline – ideal for splicing lines or extending existing oil and fuel line runs
• Vibra-Lok sleeves on both ends eliminate micro-leaks caused by vibration in metal-on-metal compression connections
• Brass body for corrosion resistance in oil, fuel, and coolant applications
• Symmetrical tube-to-tube design – same tube OD accepted on both sides

Technical Specifications

• Body Material: Brass
• Shape: Straight coupling (union)
• Connection 1 (Compression): 3/8-inch tube OD
• Connection 2 (Compression): 3/8-inch tube OD
• Style: Tube to Tube

Fitment Notes

• Both ends accept 3/8-inch OD tubing – tubing OD must match exactly on both sides
• No NPT threads – this is a tube-to-tube fitting; not for threading into engine cases or petcocks directly
• Replace Vibra-Lok sleeves (60VL-6 Buna-N or 60VLV-6 Viton) separately if sealing performance deteriorates
