Fasteners for high-pressure installations - 700bar. Larzep provides high quality at an affordable price.
LARZEP Fittings – fittings, adapters, and hydraulic quick couplers 700 bar
LARZEP fittings (AZ series) are specialized fasteners, transition adapters, pressure gauge connections, screw-to-connect quick couplers, and control valves designed for the construction and expansion of ultra-high-pressure hydraulic systems operating at a working pressure of up to 700 bar (70 MPa / 10,000 PSI). Spanish manufacturer Larzep Hydraulic (part of the globally known Enerpac group) provides reliable pressure fittings for safe connection of manual and electric pumps, hydraulic cylinders, flexible hoses, pressure gauges, and manifold blocks. AZ series fittings are made of high-strength tool steel with anti-corrosion protection, which guarantees 100% mechanical tightness on NPT tapered threads and exceptional resistance to pressure surges and shocks. Using original Larzep fittings eliminates the risk of dangerous oil leaks at 700 bar pressure and provides the basis for safe tool operation in heavy industry, construction, energy, and mechanical workshops.
Application and types of accessories in the LARZEP Fittings category
A wide range of Larzep AZ series fasteners allows for easy configuration of any power supply and control system for hydraulic cylinders. Depending on the application needs, this group includes:
- NPT/BSP nipples and straight adapters (e.g., AZ1102, AZ1113): Transition fittings made of high-strength steel with male and female threads (3/8" NPT x 3/8" NPT or 3/8" NPT x 1/4" BSP) for efficient connection of hoses, pumps, and cylinders.
- Pressure gauge connections (e.g., AZ1502): Three-way connection blocks (3/8" NPT male – 3/8" NPT female x 1/4" NPT female) allowing for easy installation of a pressure gauge into the pressure system without the need for modifying the installation.
- 700 bar screw-to-connect quick couplers (e.g., AZ3140, AZ3141): High-flow quick couplers (up to 40 l/min) equipped with 3/8" NPT threads, guaranteeing safe and fast connection of pressure lines without the risk of air entering the circuit.
- Throttling and control valves (e.g., AZ5121): Precision 3/8" NPT needle valves used for precise control of the cylinder extension or retraction speed and for holding suspended loads.
Why choose LARZEP fittings in the HYDRON store?
All Larzep fittings and adapters offered in the HYDRON store are characterized by perfectly manufactured NPT tapered and BSP parallel threads, ensuring excellent connection tightness at pressures reaching 700 bar. These components are fully compatible with hydraulic equipment from Larzep and Enerpac brands. Properly selected fittings guarantee stable working medium flow rates and eliminate pressure drops in the line. For the comprehensive construction and servicing of industrial pressure sets, we recommend selecting other compatible products from our offer, such as original Enerpac and Larzep hydraulic tools and cylinders, glycerin Larzep 700 bar pressure gauges, flexible 700 bar high-pressure hoses and lines and reliable hydraulic quick couplers.

Frequently Asked Questions (FAQ)
What are Larzep AZ series hydraulic fittings used for?
Larzep AZ series fittings are used for safe connection of hydraulic pumps, cylinders, pressure hoses, pressure gauges, and valves in ultra-high-pressure hydraulic power systems operating at pressures up to 700 bar.
What is the Larzep AZ1502 pressure gauge connection used for?
The AZ1502 connection is a special reduction block connected into the 3/8" NPT supply line, which has a side outlet with a 1/4" NPT internal thread. It is used for safe mounting of a glycerin pressure gauge (e.g., Larzep AV10007) for ongoing pressure and tonnage monitoring.
Can Larzep 700 bar quick couplers (AZ3140 / AZ3141) be disconnected under pressure?
No. 700 bar screw-to-connect quick couplers are designed for connection and disconnection only after the pressure in the system has been reduced to zero. Disconnecting the circuit under full working pressure is unacceptable for safety reasons.
Do Larzep fittings fit Enerpac devices and pumps?
Yes. Since Larzep belongs to the Enerpac group, fittings and adapters of both brands use the same normalized 700 bar (10,000 PSI) pressure standard and 3/8" NPT threads, ensuring their full interchangeability and compatibility.
