Oatey’s gray 1 oz pipe joint compound is a non-hardening paste designed to seal and lubricate threaded joints. It is suitable for water, steam, or air lines and is formulated to be non-separating and non-toxic. Its smaller size makes it convenient for compact projects or when resealing multiple connections in a tight space, ensuring consistent performance without excessive material waste.
Permatex 80045 Pipe Joint Compound
Permatex 80045 is a universal sealant designed for water, oil, and fuel lines. It lubricates and seals threaded joints and remains non-hardening for easy disassembly, which is a key advantage in maintenance and future disassembly tasks. Its resilience across a variety of fluids makes it a versatile choice for automotive, home, and workshop piping applications, though users should ensure material compatibility with their specific piping system.

It is blue, flexible, non-hardening, non-separating, and non-toxic, with no odor, making it appealing for indoor installations where odor control matters. It is compatible with multiple pipe materials, including PVC, CPVC, ABS, polyethylene, polypropylene, iron, steel, copper, or brass threads up to 2 inches in diameter, offering broad applicability.
Buying Guide
- Material compatibility: Ensure the compound is suitable for your pipe material (PVC, CPVC, ABS, metal) and for the fluids involved (water, oil, fuel, gas).
- Ease of disassembly: If you anticipate future repairs or upgrades, choose a non-hardening formula designed for easy disassembly.
- PTFE enhancement: PTFE or PTFE-like formulations generally provide smoother threading and reduce galling, beneficial on tight or corroded threads.
- Color and odor: While color is mainly for identification, some users prefer odorless products for indoor use, especially in basements or living spaces.
- Volume and coverage: For small DIY jobs, a 1–4 oz tube/paste may suffice; for larger projects, consider 8–16 oz bottles to minimize restocking.
- Temperature and pressure tolerance: Check specifications for gas vs. liquid lines and the operating temperature range to prevent joint failures under extreme conditions.
- Manufacturing origin and brand reliability: Domestic manufacturing or well-known brands can offer peace of mind regarding consistency and availability.
When selecting a pipe joint compound, align the choice with the specific piping system, expected pressure, and maintenance needs. For simple household repairs, a non-hardening, easy-to-clean paste is often sufficient. For more demanding installations, a PTFE-enhanced formula or a universal sealant that resists a range of fluids provides greater flexibility and resilience. Always follow the manufacturer’s application guidelines and local plumbing codes to ensure a reliable seal.
