STS VF/SS Stainless-Steel Breather Vent Fitting
Replacement breather vent fitting for STS Dri-Box termination enclosures used with vented level/pressure sensors. Manufacturer identifies the VF/SS fitting as a replaceable accessory; confirm thread size, enclosure compatibility and condensation protection before specification.
Technical source and compatibility
Original STS VF/SS accessory page and available product datasheet.
Engineering/safety notice: This is an installation accessory, not a sensor or intrinsically safe interface by itself. Do not assume ATEX, IECEx or FM certification without the exact ordered assembly’s approval. Follow the manufacturer’s installation instructions and environmental protection requirements.
VF/SS breather fitting service
This is a replacement vent fitting for a pressure reference enclosure, not a measuring sensor. Confirm thread size and the original Dri-Box assembly before substitution, and establish how its breather passage stays protected from splashing or condensate. A blocked or wet pressure-reference path can bias vented hydrostatic readings. Do not treat the fitting alone as certified explosion-protected equipment.
