Product questions
What gasket materials and connections can a published reference 20539 seal?
A published reference describes 20539 as a coating and sealant for gaskets including paper, felt, rubber and composition materials. It also lists hose connections and light-duty threaded connections. Confirm the gasket material and equipment manufacturer’s requirements before use.
Can a published reference 20539 be used on a paper engine gasket?
Paper gaskets are among a published reference suggested applications, but the product is intended for low-pressure service and is not automatically suitable for every engine joint. Check the equipment maker’s instructions; provide the model and serial number to verify the intended application.
What temperatures and fluids can a published reference 20539 withstand?
A published reference lists a temperature range of -65°F to 350°F (-54°C to 177°C) and resistance to diesel fuel and most automotive shop fluids. Resistance does not establish suitability for every fluid or pressure; check the specific operating conditions.
Does a published reference 20539 stay flexible, and are there uses to avoid?
A published reference describes the sealant as hard-setting but flexible when dry. Its technical data sheet says it is not recommended for pure or oxygen-rich systems or for chlorine and other strong oxidizers. The liquid and vapor are flammable; review the safety data sheet before handling.
