5/16" Compression to 3/8" Power Steering Hose Fitting

A 5/16" compression to 3/8" hose fitting designed to connect 5/16" rigid steel tube to 3/8" OEM-style power steering hose. This fitting is crimped onto the hose end and uses a compression connection on the tube end, making it ideal for power steering line repairs, extensions, or custom builds where a smaller diameter rigid tube meets flexible hose.

Key Specifications

• Connection 1: 5/16" compression (for rigid steel tube)
• Connection 2: 3/8" power steering hose (crimped)
• Hose Compatibility: 3/8" power steering hose
• Fitting Type: Compression to crimped hose
• Application: Connecting 5/16" rigid power steering tube to 3/8" flexible power steering hose

What is a Compression Fitting?

A compression fitting connects to rigid tube by compressing a ferrule (olive) around the tube as the fitting nut is tightened, creating a secure, leak-free seal without welding or flaring. This makes it ideal for field repairs and custom line builds where rigid tube needs to transition to flexible hose.

5/16" vs 3/8" Compression

This fitting uses a 5/16" compression connection on the tube end, making it the correct choice when your rigid power steering tube is 5/16" diameter. If your rigid tube is 3/8" diameter, please see our 3/8" compression to 3/8" power steering hose fitting instead.

Custom Hose Builds

If you require a complete custom power steering hose with this fitting, it can be supplied pre-crimped when purchased together with our 3/8" power steering hose. Please get in touch with your hose build requirements and we'll be happy to assist.
