Purpose-built pipe thread sealant

Krytox TS4 is a white PTFE-based sealant supplied in an 8 fl oz tube. It is formulated for general-purpose thread sealing on metal and plastic piping systems. The compound handles a wide range of fluids including fuels, gases, oxygen, steam and water. It suits maintenance engineers and plant operators who need reliable sealing across diverse chemical environments.

Temperature and pressure envelope

The sealant operates continuously from -65 degrees F up to 300 degrees F. It is rated for gaseous service up to 400 psi. Within these limits it maintains integrity on threaded joints carrying acetone, alcohol, butane, ethanol, natural gas, propane and similar media. Outside this envelope the material may degrade or lose sealing capability, so it is not suited for higher-pressure gas lines or extreme thermal cycling beyond the stated range.

Standard compliance and chemical limits

The product follows ASNI/ASME Guideline B. 20.1 -1983 for thread sealing practice. Its PTFE chemical base resists attack from the listed fluids but is not certified for every industrial chemical or potable water standard not referenced in the data. Installers must verify compatibility with any specific fluid or regulatory requirement not explicitly covered by the manufacturer highlights.

Questions about this item

Will the Krytox TS4 sealant hold up on my older brass fittings that see both -65 °F and 300 °F?

Yes — it is rated for continuous service from -65 °F to 300 °F and seals metal threads including brass.

How can I confirm the sealant is performing correctly after I assemble the joint?

Pressurise the system up to 400 psi with gas; a leak-free joint at that pressure shows the PTFE paste is working.

Does the 8 fl oz tube include an applicator tip or do I need a separate caulking gun?

The product ships as an 8 fl oz squeeze tube with no separate gun or tip included.
