High-Pressure Sights
For Clear Liquid
For Dark Liquid
With a thick glass window fused to a metal body, these sights resist cracking at high pressures.
Sights for dark liquid have a reflector that makes liquid easy to see, especially in low-light conditions.
2205 stainless steel sights are more corrosion resistant than nickel-plated steel sights.
