Glycerin filling sets this gauge apart for demanding hydraulic service, the fluid dampens vibration, absorbs sudden pressure spikes, and protects internal sensing components from moisture, extending service life in high-cycle or harsh environments. The Enerpac Hydraulic Pressure Gauge, 2.50 in. Face, Lower Mount, Glycerine Filled, 10,000 maximum psi belongs to the G-Series and is rated to a maximum working pressure of 10,000 psi (700 bar). The lower-mount connection allows direct inline installation, and the 2.50-inch face provides a clear, readable dial in space-constrained mounting locations.
The dual-scale face displays readings in both psi and bar, supporting use in applications where either unit is required. A built-in safety blow-out disk and pressure equalizing membrane are included as standard features. For applications involving rapid pressure cycling, pairing the gauge with a snubber or needle valve is advisable to further protect the sensing element.
gauge says glycerine filled -- does that actually help with pressure spikes or is it mostly just for vibration?

Both, really. The glycerine dampens the needle movement during vibration and also cushions the sensing parts when pressure surges hit hard and fast. Without it, those spikes can wear out the internals pretty quick. For anything running high cycles though, the product does recommend pairing it with a snubber or needle valve on top of the fill -- the glycerine alone isn't a substitute for that on real punishing applications.

running a log splitter and the needle chatters when the valve snaps shut. will the glycerin fill help calm that down some?

Glycerin inside the gauge dampens the movement of the pressure sensing parts, so it helps protect against vibration and sudden pressure changes. That usually makes the pointer steadier and can cut down on chatter compared to a dry gauge.
