High Temperature Silicone Fluid


Ships on the same business day if the order is placed before 10:00 a.m.

Beaker & Wrench® offers a silicone based fluid that is ideally suited for high oxidation or complete exposed systems, like open baths. This fluid is ideal for jacketed circulators utilizing high temperatures and long term use. This product is long lasting because it is impermeable to oxidation at temperatures under 204°C (400°F). So long as it is not contaminated and operating within the specifications of the safety data sheet, the fluid will maintain long lasting integrity.

When purchasing, use drop down tab to indicate whether you would like 1 gallon or 5 gallons.
