HILTAP LQC Coupler Animation

Demonstration of Competitive CAMLOK Disengaging at 60 psi

Unlike competitors of OPW Engineered Systems, our Kamlok will not allow users to accidentally disengage a valve with pressure in the line. As the video demonstrates, disengaging a locked coupler with active line pressure could cause serious injury or even death.

Demonstration of Twister LQC at 60 psi

This video shows OPW Engineered Systems' Twister LQC staying connected due to active pressure within the line. Even though the operator attempts to disengage the connection, he is unable. It is only after the pressure is removed from the line, the connection disengages. This safety feature helps protect the operator from pressure discharge and exposure to the commodity inside the connection.

Offloading of Railcar with OPW's LQC

Workers prepare to offload a commodity from a railcar using OPW Engineered Systems' Locking Quick Connect (LQC). The operator is able to quickly connect, twist and engage the connection without any special tools - saving time and increasing safety.

Animation of OPW's LQC in Action

The animation shows how OPW Engineered Systems' Locking Quick Connect (LQC) remains engaged even if the locking notch releases. This enhanced safety device means operators can count on the LQC to reduce the probability of accidental disconnection and keep the product contained.
