Structure and Materials
The 91N Series Crimp Style Hydraulic Hose Fittings are precision-engineered components designed specifically for SAE 100R14 PTFE hoses. Their structure ensures excellent sealing, durability, and compatibility with high-temperature and chemically aggressive environments.
One-Piece Crimp Design
The fitting features a one-piece construction that eliminates brazed or welded joints, minimizing potential leak paths and improving overall strength and reliability.
Deep Serrated Hose Insert
The hose insert has finely machined serrations that grip the PTFE hose liner and stainless steel braid securely, preventing slippage under high pressure or temperature cycles.
Smooth Bore Transition
A gradual internal transition between the hose and fitting maintains smooth fluid flow, reducing turbulence, pressure loss, and contamination buildup.
Precision Machined Hex Body
The body is machined with tight tolerances and a metric or inch hex for easy installation using standard tools, ensuring a consistent torque and secure connection.
High-Quality Material Construction
Made from 316 stainless steel or nickel-plated carbon steel, providing superior corrosion and chemical resistance even in caustic or outdoor conditions.
Crimp Ferrule Section
The ferrule portion is specifically designed to evenly compress around the PTFE hose during crimping, ensuring a uniform seal and permanent, vibration-resistant connection.
Multiple End Configurations
Available in straight, 45°, and 90° elbow configurations, with a range of end connections such as JIC, BSP, NPT, ORFS, and Metric threads, allowing flexible system integration.
The 91 series crimp fittings are widely used in industries where safe, leak-free connections are critical, especially in environments exposed to high pressure, vibration, or aggressive chemicals. Their versatility and robust design make them a trusted choice across multiple fields:
Chemical Processing
With stainless steel and corrosion-resistant options, the fittings are well suited for handling aggressive chemicals, solvents, and corrosive fluids. They are commonly installed in processing plants, chemical transfer systems, and laboratories where contamination control is essential.
Automation & Testing Equipment
Reliable connections are vital in automated machinery and precision test rigs. The 91 Series delivers consistent performance, supporting stable operation in equipment that requires repeatability and accuracy, such as robotic arms, hydraulic presses, and fluid test benches.
Marine & Offshore
Stainless steel versions provide superior corrosion protection in seawater and offshore oilfield environments. These fittings are used in ship hydraulics, offshore platforms, and subsea equipment, where both safety and reliability are non-negotiable.

FAQ
What hoses are compatible with 91 series crimp fittings?
The 91 Series is designed for use with hydraulic hoses and PTFE hoses. Always check the hose size and pressure rating to ensure proper compatibility.
What pressure ratings can the fittings handle?
Pressure capability varies by hose size and material but generally supports medium-pressure applications up to approximately 3000 psi. Always confirm with the hose and fitting specification charts.
What materials are available?
The 91 Series is available in carbon steel, brass, and stainless steel. Stainless steel versions are recommended for corrosive or marine environments.
Do I need to skive the hose before crimping?
No. The 91 Series is a no-skive fitting, meaning the hose does not require skiving before assembly, which saves time and reduces the chance of errors.
Can I install the fittings without special tools?
The fittings must be installed with a proper crimping machine.
What industries use 91 series crimp fittings most often?
Common industries include construction, agriculture, aerospace, defense, chemical processing, automation, and marine applications.
