Vacuum valve fitting for older housings without a spare 13/8" diameter accessory port. The valve's low profile avoids interference with control operation. The included waterproof plug is secured to the fitting to prevent accidental loss. Vacuum pump sold separately.
Compatibility
Most newer housings with an opaque white front feature a spare 1/2-20 threaded accessory port. The plug of this spare port may be replaced with this vacuum valve.
Additionally, it can be installed in place of the 1/4-20 top mount featured on all DSLR housings produced since 2009.
