Midland Industries LSQVEP12SF Quick Coupler 1/2in Female Npt

Product Description

The MIDLAND INDUSTRIES LSQVEP12SF is a flat face thread lock quick coupler designed for hydraulic systems requiring a secure, leak-resistant connection. Part of the LSQ-VEP Series, it features a 1/2-inch body with a 1/2-inch female NPT port and a 1/2-14 thread specification. The flat face design minimizes fluid spillage and air inclusion during connect and disconnect cycles, making it well suited for mobile hydraulic equipment and stationary hydraulic power units. Rated to 4000 psi maximum operating pressure, this coupler is built from steel for durability under demanding service conditions. Licensed hydraulic technicians and equipment mechanics are the typical installers.

This coupler is used in hydraulic circuits where a reliable, flat face quick disconnect is required. The thread lock mechanism prevents accidental disconnection under pressure fluctuations or vibration, which is common in construction equipment, agricultural machinery, and industrial hydraulic systems. The operating temperature range of -20 to 120 degrees C makes it suitable for both cold-weather outdoor applications and heated industrial environments. It fits into systems where 1/2-inch NPT female porting is standard on cylinders, valves, or manifold blocks.

Key Features

• Flat face design minimizes fluid loss and contamination during coupling and uncoupling
• Thread lock mechanism prevents accidental disconnection caused by vibration or pressure surges
• 4000 psi maximum operating pressure rating for high-demand hydraulic circuits
• 1/2-inch female NPT port for direct connection to standard NPT-ported hydraulic components
• Steel construction provides resistance to wear and mechanical stress in field conditions
• Wide operating temperature range of -20 to 120 degrees C for varied environments

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic quick disconnect applications using 1/2-inch female NPT connections in the LSQ-VEP flat face thread lock series.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanic. Fully depressurize and relieve all residual hydraulic pressure from the system before disconnecting or installing any coupler. Clean mating surfaces and threads before assembly to prevent contamination from entering the hydraulic circuit. Follow applicable equipment manufacturer torque guidelines and consult relevant hydraulic system service documentation for proper assembly procedures.
