Description
Custom CNC Turned Stainless Steel Ferrule & Pipe Fitting Components
Precision CNC machined tube fitting and ferrule parts in SS304, SS316, brass, and custom alloys for industrial fluid systems and high-pressure applications.

Product Overview
CNC turned ferrules and pipe fitting components are precision-machined parts used in fluid transfer and tubing connection systems. These components require tight dimensional control, smooth sealing surfaces, and reliable material performance to ensure leak-free operation under pressure.
Our custom manufacturing capabilities allow us to produce these parts to your exact specifications, whether you need standard sizes or custom designs for unique application requirements. We work with a wide range of materials to meet the demands of various industries and environments.

What Is CNC Turning for Tube Fittings?
CNC turning is a subtractive manufacturing process where rotating metal stock is machined using precision cutting tools. For ferrules and tube fittings, this process ensures exceptional concentricity, consistent surface finish, and precise dimensional accuracy required for reliable sealing performance.
Unlike traditional manufacturing methods, computer-controlled turning allows us to produce complex geometries with repeatable accuracy, even for large production runs. This ensures every part in your order matches the exact specifications of your design, eliminating variability that can cause system failures.
Material Selection: SS304 vs SS316
When it comes to high-pressure and corrosive environments, material selection is critical. The right material ensures your fittings will perform reliably over their service life, even in harsh conditions.
SS316 stainless steel, often referred to as marine-grade stainless steel, contains molybdenum, which significantly enhances its resistance to chloride corrosion and aggressive chemicals compared to standard SS304. This makes it the ideal choice for chemical processing, marine applications, and other harsh environments where standard materials would fail.

Dual Ferrule Design Explained
Our dual ferrule system features two precision-machined components: the front ferrule and the rear ferrule, which work together to create a reliable, leak-free seal that performs under extreme conditions.
The front ferrule creates the primary seal against the tube body, while the rear ferrule provides secure grip and support to prevent tube pull-out, even under high pressure and vibration. This proven design ensures consistent performance in critical applications where system failure is not an option.

Frequently Asked Questions
What is the difference between CNC turning and milling?
CNC turning works with rotating material to create cylindrical parts, which is ideal for tube fittings and ferrules that require round, concentric dimensions. Milling uses a rotating tool on stationary material to create complex non-cylindrical shapes. For pipe fitting components, turning is the optimal process to ensure the precision required for sealing.
Why choose SS316 for pipe fittings?
SS316 contains molybdenum, which gives it superior corrosion resistance compared to standard SS304, especially against chloride and chemical exposure. This makes it perfect for marine environments, chemical processing, and other harsh conditions where standard stainless steel would corrode over time.
What tolerance can CNC turned fittings achieve?
Our standard tolerance for CNC turned fittings is ±0.01 mm, which is more than sufficient for most industrial applications. For more critical applications, we can achieve tighter tolerances upon request, depending on the part size and material.
Can you manufacture based on custom drawings?
Yes, we specialize in custom manufacturing based on customer drawings. We accept 2D CAD files and 3D models, and our engineering team will review your drawings to ensure manufacturability before production starts. We can produce both small prototype runs and large volume orders.
What is your MOQ and lead time for custom parts?
Our minimum order quantity for custom parts is flexible, we can accommodate small prototype orders as well as large production runs. Typical lead time for custom parts is 15-25 days, depending on the part complexity and order quantity. We can also offer expedited service for urgent requests.
