High-Performance 15l Hydraulic Fitting for Demanding Industrial Applications
In high-pressure hydraulic systems, the integrity of every connection is paramount. Our 15l hydraulic fitting is engineered to meet the rigorous demands of modern industrial machinery, providing a reliable, leak-free seal that ensures optimal system performance and longevity. Designed for compatibility with SAE 15L flareless bite-type tubing, this fitting is a critical component for builders and maintainers of hydraulic systems in construction, agriculture, manufacturing, and beyond.
Product Overview
This professional-grade 15l hydraulic fitting is manufactured to exacting standards, creating a robust mechanical grip on tubing without the need for flaring. The "bite-type" design allows for a simpler, faster, and more reliable installation compared to traditional flare fittings, making it a preferred choice for OEMs and maintenance teams worldwide. It is specifically designed to form a superior seal with SAE 15L specification tubing, ensuring compatibility and performance in a vast array of hydraulic circuits.
Key Features
- Flareless Bite-Type Design: Eliminates the need for tube flaring, reducing installation time and potential points of failure. The ferrule mechanically bites into the tube for a secure, vibration-resistant hold.
- High-Pressure Rating: Engineered to withstand extreme system pressures, ensuring reliability in the most demanding hydraulic applications.
- Superior Sealing Technology: Features a precision-engineered ferrule and nut assembly that creates a multi-point seal, effectively preventing leaks and fluid loss.
- Robust Construction: Manufactured from high-grade steel or stainless steel, offering excellent resistance to corrosion, wear, and environmental stress.
- Wide Compatibility: Specifically designed for use with SAE 15L tubing, making it a versatile component for system upgrades, repairs, and new builds.
- Reusable Design: In many configurations, the fitting can be disassembled and reassembled multiple times without compromising its sealing integrity, ideal for modular systems.

FAQ
What does "15l" refer to in a 15l hydraulic fitting?
"15L" refers to the SAE (Society of Automotive Engineers) standard for hydraulic tubing. SAE 15L specifies the dimensions, tolerances, and material requirements for seamless carbon steel tubing used in hydraulic fluid power systems. This fitting is specifically engineered to create a seal with tubing that meets this standard.
Can I use this fitting with other types of tubing?
It is strongly recommended to use this fitting only with tubing that meets the SAE 15L specification for which it is designed. Using incompatible tubing (e.g., different wall thickness or hardness) will compromise the bite seal, leading to potential leaks and system failure.
How do I properly install a flareless bite-type fitting?
Proper installation is key. Ensure the tube end is cut square and deburred. Insert the tube into the fitting body until it bottoms out. Hand-tighten the nut, then use a wrench to turn the nut the specified number of turns (typically 1-1/4 to 1-1/2 turns). This action draws the ferrule into the body, causing it to bite into the tube and form the seal. Over-tightening can damage the fitting.
What is the difference between ORFS and NPT thread types on these fittings?
ORFS (O-Ring Face Seal) fittings have a straight thread and seal via a flat face with an O-ring, offering excellent leak-free performance and are reusable. NPT (National Pipe Tapered) fittings seal through thread interference (using thread sealant) and are common in North America. The choice depends on your system design and regional standards.
Do you offer certifications for your fittings?
Yes. We can provide material certifications (e.g., 3.1 Material Test Certificates per EN 10204) and other relevant documentation upon request to support your quality management and traceability requirements.
