Is the Adaptor for pressure gauge FT 299, carbon steel available in AISI 316 stainless steel upon special request?

Yes. The Adaptor for pressure gauge FT 299, carbon steel is available upon special request in AISI 316 stainless steel. The standard material is galvanized steel with NBR sealing and an operating temperature range of -20Â°C to +100Â°C.

Can the rotating nut on the Adaptor for pressure gauge FT 299, carbon steel be adjusted while the system is pressurized?

No - the rotating nut on the Adaptor for pressure gauge FT 299, carbon steel should not be adjusted while the system is pressurized. The adapter is designed for direct connection and includes a small orifice to dampen pressure spikes, but the rotating nut is for positioning the gauge and relies on proper sealing (NBR) and thread engagement. Adjusting it under pressure risks oil leakage, seal failure, and personal injury. Isolate and depressurize the system before repositioning or tightening the nut.

How does the small hole in the Adaptor for pressure gauge FT 299, carbon steel reduce pressure spikes in the hydraulic system?

The small hole in the Adaptor for pressure gauge FT 299, carbon steel acts as a flow restrictor between the hydraulic system and the gauge. When a rapid pressure spike (e.g., from pump starts, valve slams, or load shocks) reaches the adapter, oil can only pass through that tiny orifice at a limited rate. This restricted flow creates a cushioning effect: the gauge sees pressure changes more slowly because the orifice and the trapped volume between system and gauge form a simple hydraulic damper. The result is reduced amplitude and shorter-duration jolts transmitted to the gauge mechanism, protecting it from needle flutter, overshoot and mechanical damage while still allowing the gauge to indicate steady-state and slower pressure variations accurately. The rotating nut on the adapter enables correct orientation of the gauge without compromising this damping function.
