Vacuum valve fitting for any housing with a spare 1/2" accessory port. Additionally, it can be installed in place of the 1/4-20 top mount featured on all DSLR housings produced since 2009.

The valve's low profile avoids interference with control operation. The included waterproof plug is secured to the fitting to prevent accidental loss. Includes vacuum pump with gauge.

This valve is installed quickly and easily by securing one nut on the inside of the housing. The housing does not need to be returned to the factory for installation.
