Industrial pressure gauge 0–300 psi

The Ashcroft 251009 is a 2-1/2 inch dial gauge rated for 0 to 300 psi with a ±1.5 percent accuracy. A 304 stainless steel case and polycarbonate lens resist corrosion in harsh environments. It suits technicians monitoring hydraulic, pneumatic or process systems where reliable local indication is required.

Verify connection and sealing method

Confirm the 1/4 inch male NPT thread matches your port before ordering. The gauge is field fillable for liquid damping if vibration resistance is needed later. Note the IP rating changes with the vent plug: IP54 when vented and IP65 or NEMA 4 when the plug is closed.

Stainless construction and bottom mount

The 304 stainless case and metallic finish withstand chemical splash and outdoor exposure. A bottom-mounted process connection keeps the dial upright on horizontal pipe runs. The polycarbonate lens resists impact better than glass while the vent plug lets you choose between pressure relief and full ingress protection.

Questions about this item

What comes with the Ashcroft 251009 gauge and do I need to buy a fitting?

The gauge includes a 1/4 in MNPT bottom connection and a polycarbonate lens; no separate fitting is required if your port matches 1/4 in NPT male threads.

Should I choose the vented IP54 or sealed IP65 version for a wash-down area?

With the plug closed the gauge meets IP65 and NEMA 4, so select the sealed configuration for wash-down or wet environments.

What does the ±1.5 % accuracy mean when the gauge reads 300 psi?

At full scale the true pressure will be within 4.5 psi of the indicated value, giving a reliable reading across the 0 to 300 psi range.
