Can I use the ORFS pressure gauge connection with GW BSP in carbon steel, type MAV-B, sealed with a metal washer in high-vibration applications?

Yes, you can use the ORFS pressure gauge connection with GW BSP in carbon steel, type MAV-B in high-vibration applications, with reservations. The MAV-B (Straight ORFS pressure gauge connection with internal BSP thread, sealed with a metal washer; carbon steel, galvanized) provides a robust metal-to-metal washer seal and strong carbon steel body-both advantageous for vibration resistance. However, success depends on correct installation (proper torque, clean threads, and correct washer seating), appropriate thread-locking or lockwire if needed, and matching pressure/vibration specs of your system. For severe vibration or dynamic loads, consider additional anti-vibration measures (flexible hose, vibration isolator) or a dedicated vibration-rated connector. Verify compatibility with your systemâs pressure, temperature, and media, and consult manufacturer limits or perform testing for critical applications.

Is the ORFS pressure gauge connection with GW BSP in carbon steel, type MAV-B compatible with hydraulic fluids containing glycol?

Probably not recommended without confirmation from the manufacturer. Reasoning: - The product named ORFS pressure gauge connection with GW BSP in carbon steel, type MAV-B Format is made of carbon steel, galvanized. Carbon steel itself is generally compatible with many hydraulic fluids, including glycol-based fluids (water-glycol), but galvanizing (zinc coating) can be sensitive to certain fluids. - Water-glycol fluids are more corrosive and hygroscopic than mineral oils and can promote corrosion if the steel or its coating is not specifically qualified for such fluids. Zinc coatings may suffer accelerated corrosion or chemical attack depending on fluid formulation, pH, and additives. - Seal material and thread sealing method matter: the described connector is sealed with a metal washer. Metal-to-metal sealing offers good mechanical integrity but provides no chemical barrier; any corrosion of the washer or mating surfaces can compromise the seal over time when exposed to water-glycol fluids. - Temperature, pressure, and fluid contamination (water content, microbes, additives) also affect compatibility and corrosion risk. Recommendation: - Verify with the manufacturer/supplier whether the ORFS pressure gauge connection with GW BSP in carbon steel, type MAV-B Format is qualified for use with specific water-glycol (glycol-containing) hydraulic fluids, including details on permissible fluid types, concentrations, temperature and pressure limits, and expected service life. - If manufacturer data are unavailable, consider using a connector specified for water-glycol fluids (stainless steel or compatible coatings and appropriate sealing materials) to ensure long-term corrosion resistance and seal integrity.

ORFS pressure gauge connection with GW BSP in carbon steel, type MAV-B

Q: What is the correct torque for installing the ORFS pressure gauge connection with GW BSP in carbon steel, type MAV-B, sealed with a metal washer?

The correct installation torque for the ORFS pressure gauge connection with GW BSP in carbon steel, type MAV-B (sealed with a metal washer) is 30â40 Nm (22â30 ftÂ·lb). Tighten progressively to specified torque to ensure proper metal-washer sealing; avoid over-torquing which can damage threads or deform the washer. If assembling into a softer material or into components with different specifications, consult the equipment manufacturer's torque recommendations and apply a calibrated torque wrench.
