Threaded Quick Couplings for Hydraulic Solutions

Threaded quick couplings provide hydraulic solutions to pressurized applications or where pressure exists in a line. These applications pose a risk to worker safety and environmental contamination. Protect your employees and the environment with threaded quick couplers designed for leak free performance upon quick connect and quick release processes

Threaded hydraulic couplings eliminate premature brinelling and signs of early wear and tear.  Be sure to speak with a hydraulic connection expert to select the right threaded quick coupler for your process. Choosing the right quick coupling will maximize your productivity, efficiency and safety.

Stucchi Offers Reliable Threaded Quick Couplings

Stucchi is known as an authority on hydraulic quick connect solutions, with nearly 60 years in business and vast resources to meet any hydraulic quick coupler need. Our threaded quick couplers are proven in several case studies and applications worldwide to improve process performance and overall business operations resulting in increased profitability. Our most popular threaded couplings include the following flat face threaded couplers:

VEP – provides reliable hydraulic connection in pressurized applications or where residual or trapped pressure exists in a line.

VEPHD – the VEP engineered with upgraded material for a heavy duty model which meet the demands of rugged applications.

VEPHDL – all the benefits of the VEPHD with the added assurance of a locking quick coupler. This threaded coupling delivers failsafe hydraulic connections with interchangeable female locking components.

VP – a popular threaded coupling providing auto locking features and safety in pressurized applications.

Hydraulic Check Valves Protect against Fluid Back Pressure

Hydraulic check valves protect against damage caused by fluid back pressure and may be adjusted to use as a pressure sequence valve.  Stucchi offers a wide selection of hydraulic check valves in various materials to meet specifications of any hydraulic circuit.  Our check valves are found in a multitude of industrial applications worldwide and include the following:

VU– The VU series of hydraulic check valves is constructed of steel with black phosphate with the option of zinc plating. Sizes range from 1/4" to 2” with two standard openings of 5 to 65 psi. The internal spring loading may be adjusted to the required cracking point for use as a pressure sequence valve.

VUX SERIES – Stucchi’s VUX series is available with a standard opening of 7.5 psi in a compact design. The internal spring loading may be adjusted to the desired cracking point when used as a pressure sequence valve.  The VUX is found in industrial equipment, mobile equipment, and oil and gas applications worldwide.

VUZ Series – The VUZ series is similar to the VU series, with two standard openings of 5 to 65 psi.  The VUZ is constructed in carbon steel and safe for noncorrosive hydraulic processes. 

Stucchi provides proven hydraulic solutions with these check valves and a wide selection of hydraulic quick couplers.  Our vast resources and in-depth expertise allows us to provide quick turnaround with exceptional customer service. Our skilled engineers are the best in the business and assist customers in selecting the right quick couplers for your application to maximize productivity and equipment uptime.

Our product line includes proven flat face couplers, threaded couplings, poppet and threaded poppet interchange couplers, high pressure couplers, multi-coupling plates and custom designed solutions.

Threaded Poppet Valve Couplers for Quick Release Solutions

Threaded hydraulic poppet valves provide positive stop valving to prevent flow checking in open or closed hydraulic systems.  Threaded poppet interchange couplers provide a solution for leak free interchange couplers which improve safety and efficiency. Thread to connect poppet valve couplers offer quick connect and quick release interchange solutions in processes under residual pressure.  

Threaded Poppet Couplers Proven for High Performance

Threaded hydraulic poppet couplers by Stucchi are proven in applications worldwide to save time and improve efficiency. Our threaded poppet couplers improve efficiency when interchanging on equipment lines and provide resistance to pressure in a compact design. We offer a wide selection of threaded poppet couplers to meet your specifications:

• VOF – compact design, constructed of carbon with poppet valve and elastomer seals for reliable quick release without leaks.   
• VOFX - manufactured with 316 stainless steel for high corrosion resistance, designed to reduce pressure drop and turbulence.
• WING STYLE - this rugged wing nut style delivers reliable connection under pressure with minimum air inclusion and spillage.
• VLS – provides heavy duty service with carbon construction, thread to connect design and zinc plating on the coupler body and the hardened steel nipple. Nitrile seals with Teflon anti-extrusion rings provide reliable sealing and heavy duty construction and mobile equipment operations.
• VD - also known as the European screw coupler, this threaded poppet style valve ensures reliable connection in applications with residual pressure, pressure impulses or spikes.
• VR - known as the German screw coupler, the VR series provides threaded connection with a low leakage style valve. The VR is suitable in many hydraulic applications and heavy duty processes such as industrial fields and mobile construction.

Stucchi offers these threaded poppet coupler solutions as part of a wide selection of many hydraulic couplers for virtually any hydraulic quick connect application. Our full product line includes flat face couplers, threaded flat face couplings, multi-coupling plates, poppet interchange couplers, threaded poppet couplers, check valves, dust caps and accessories.
