Double ferrule pipe fittings are precision-engineered mechanical fittings used to create leak-tight, high-pressure connections between pipes or tubes—without welding or threading the pipe ends. They are widely used in instrumentation, hydraulics, gas, and chemical systems where reliability and easy assembly are essential.
🔍 What Are Double Ferrule Pipe Fittings?A double ferrule fitting consists of:
Front Ferrule – creates a seal on the tube and fitting body
Back Ferrule – grips the tube and transfers torque
Nut – tightens and compresses the ferrules
Body – houses the tube or threaded connection
🔄 These fittings do not require welding, making them ideal for clean, maintenance-friendly systems.

| BRAND | KALPATARU |
Double Ferrule Fittings are high-quality compression fittings commonly used in instrumentation, process piping, and high-pressure fluid systems. The term “Double Ferrule” refers to the two ferrules inside the fitting — a front ferrule and a back ferrule — which work together to create a strong, leak-tight seal on tubing.
🧱 Key Features| Feature | Description |
|---|---|
| Material | Stainless Steel 316 (SS316) — excellent corrosion resistance, suitable for harsh and corrosive environments |
| Ferrule System | Two ferrules: front ferrule (seals) and back ferrule (grips the tube) |
| Tube Compatibility | Typically used with hard metal tubing (stainless steel, copper, alloy, etc.) |
| Pressure Rating | Up to 10,000 psi or higher, depending on size and manufacturer |
| Sizes Available | 1/16" to 1" (or metric equivalents like 4 mm to 25 mm) |
| Thread Types | NPT, BSPT, BSPP, and others for connection ends |
| Standards | Often built to ANSI/ASME B1.20.1, ISO, and manufacturer-specific specs |
Back Ferrule: Bites into the tube surface when tightened, holding the tube firmly.
Front Ferrule: Compresses against the fitting body, creating a metal-to-metal seal that is highly leak-resistant.
Nut: When tightened, compresses both ferrules to form a strong mechanical grip and seal.
Superior sealing and gripping strength
Better vibration resistance
Easier tube installation and removal (ferrules don’t get stuck)
Improved reliability in high-pressure applications

A double ferrule end cap made from stainless steel 304 is a type of fitting used to seal the end of a tube or pipe in a piping or tubing system that uses double ferrule compression fittings. It uses the same two-ferrule design to ensure a secure, leak-tight seal at the end of the line.
🧱 Key Features:Material: Stainless Steel 304 — good corrosion resistance for general industrial use
Design: Double ferrule system with front and back ferrules to grip and seal tubing
Function: Caps off the tube end to prevent flow or contamination
Sizes: Typically matches tubing sizes from 1/8" to 2" OD (common sizes like 1/4", 3/8", 1/2")
Provides a secure, leak-proof seal at tubing ends
Easy to install and remove without welding or soldering
Compatible with standard double ferrule fitting systems
Durable for high-pressure and moderate temperature applications
Instrumentation tubing
Chemical and petrochemical lines
Hydraulic and pneumatic systems
Food and beverage processing
Laboratory and analytical setups
