KEZE PTFE Silicone Grease Tube — Food‑Grade Lubricant for O‑Rings & Seals

Product description

This product is supplied as a single squeeze tube of clear silicone grease (model 92003), packaged for easy dispensing and spot treatment of seals and sliding parts.

Formulated as an H1 food‑grade silicone grease, the compound contains no colorants so it won’t introduce visible contaminants and is safe for incidental contact with drinking water systems. The blend includes PTFE and is telon‑based, offering chemical resistance to acids, alkalis and many organic solvents while also providing strong protection against abrasion, friction and moisture.

Temperature tolerance runs from -40° to 428° F, making the grease suitable for both cold and high‑heat environments. Typical uses include lubricating sliding glass door tracks, O‑rings, plastic components, spark plug boots, valves, rubber seals, 3D printer parts, car windows, plumbing faucets and other household or automotive fittings.

Performance is focused on lubrication and sealing between dissimilar materials: metal to rubber, metal to polymer, plastic to plastic and plastic to metal, as well as vinyl, leather and other common materials. If you encounter any issues with your 92003 tube, customer service is available to assist with replacements or refunds.

Pros

  • H1 food‑grade, clear formula — safe for incidental contact with potable water
  • Wide operating range: -40° to 428° F
  • PTFE‑enhanced for chemical and moisture resistance

Cons

  • Very tacky—can be messy to apply
  • Tube size may be small for heavy commercial use
  • Not a structural adhesive—only a lubricant/sealant

VerdictA versatile, food‑grade silicone lubricant ideal for a wide range of sealing and sliding applications. The PTFE‑enhanced, telon‑based formula resists acids, alkalis and many solvents while repelling moisture and reducing friction. It works well on rubber seals, O‑rings, plastics and metal‑to‑rubber interfaces and is stable across a broad temperature span (-40° to 428° F). Good choice for household

Reader reviews

  1. William Sullivan 5/5

    Good to have extras

    Simple clear silicone grease. I used it on door and hatch rubber seals and it performed as expected.

  2. Larry Van Brocklin 5/5

    Automotive use

    Used it when replacing sway bar bushings — worked very well and made reassembly easier.

  3. Aayan Khan 5/5

    Smooth and easy to apply

    Nicely packaged and the tube size was right. Applied to slider rails on a disc drive—now it glides like butter.

  4. Mountain View 5/5

    Perfect for door tracks

    Does exactly what I needed on sliding door rails—keeps movement smooth and quiet.

  5. Servicios I. 5/5

    Excellent for printer maintenance

    Does the job perfectly. I service printers and use this to lubricate moving parts—nothing better for that purpose.

  6. David J. Terway 5/5

    Extremely effective

    A tiny dab on the miniature rollers of my Kensington trackball smoothed the operation completely. Use a q‑tip and remove excess. Avoid optical windows. Highly recommended.

  7. Robin S. Douglas 5/5

    Ideal multipurpose lube

    Exactly what I needed. A small smear on lazy‑Susan bearings softened rotation and stopped the noise. High temp rating should keep it in place. Good value.

  8. Lhen 5/5

    Does the job

    Performed exactly as expected.

  9. D.Sreekanth Reddy 5/5

    Good O‑ring sealant

    Good quality sealant for O‑rings and seals.

  10. DTO 5/5

    Handy and versatile — second purchase

    Second time buying this and it’s great. I gave a tube to my son and he liked it. A little goes a long way—use with small brushes on hose fittings, washers, hinges, brake parts, O‑rings and window slides. I also coat battery terminals and external wiring to deter moisture. Food‑grade safety was the main reason I bought it.

  11. Ciro 5/5

    Very versatile for home and auto

    Second purchase — high quality and long lasting. Recommended for calipers, O‑rings, garden hoses, radiator hoses and hinges. Withstands high temps and I’ll buy it again.

  12. Drake 5/5

    Sticky but effective

    Sticky and holds well. Used on my RV toilet O‑ring and it solved the leak. Wear gloves—hard to wash off skin.

  13. Jennie Hunter 4/5

    Works well in RV toilet

    Has worked great so far on my camper toilet seal. I’ve only used it about a week but it’s been trouble‑free.
