The proper sealant is your secret weapon when dealing with leaks or assembling parts. Threebond products, especially 1104 and 1184, have built an excellent reputation.
Mechanics with years of experience often reach for Threebond, a choice driven by trust in its strength and reliability.
Whether you’re a seasoned professional or a weekend garage enthusiast, knowing the differences between 1104 and 1184 is crucial. This knowledge transforms a standard repair into an exceptional one.
Let’s explore what makes these sealants stand out and why they’re the go-to options for so many.
What is Threebond 1104?
Threebond 1104 is a synthetic rubber-based sealant for many automotive and industrial applications. Its formulation provides a durable, flexible seal resistant to oils, coolants, and other automotive fluids.
This sealant is particularly noted for its excellent sealing properties in low-pressure applications, making it ideal for use in places where a tight, leak-proof seal is crucial.
Mechanics and technicians often use Threebond 1104 when they need a reliable sealant to withstand the harsh conditions in engine compartments and other automotive systems.
What is Threebond 1184?
On the other side of the spectrum is Threebond 1184, a sealant revered for its strong adhesive properties and resistance to high temperatures and chemicals.
This nitrile rubber-based sealant is engineered for applications requiring a more rigid, more resistant seal. It’s especially suitable for areas exposed to high temperatures or aggressive chemicals and is often used in gaskets, flanges, and other critical engine components.
Its robust composition ensures a durable bond, making it a staple in environments where performance and longevity are paramount.
How are they different?
• Chemical Composition: While Threebond 1104 is synthetic rubber-based, 1184 is formulated with nitrile rubber, influencing its resistance and durability under different conditions.
• Temperature Resistance: Threebond 1184 withstands higher temperatures than 1104, making it suitable for engine parts that experience intense heat.
• Flexibility vs. Strength: 1104 offers more flexibility, making it ideal for parts that might experience movement or vibration, whereas 1184 provides a more formidable seal for stationary components.
• Application Suitability: Threebond 1104 is preferred for low-pressure applications, while 1184’s robust nature suits it for high-pressure environments.
• Chemical Resistance: 1184 generally offers superior resistance to oils, fuels, and other harsh chemicals compared to 1104, making it better for more aggressive environments.
How are they similar?
• Purpose: Both are designed to seal and protect components, ensuring reliable operation and preventing leaks.
• Brand Reputation: As Threebond products, they carry a reputation for quality and reliability, trusted by professionals globally.
• Versatility: Both sealants are versatile and used across various automotive and industrial applications.
• Ease of Use: Each can be applied quickly and cures to form a durable seal, making them user-friendly for professionals and amateurs alike.
• Resistance to Automotive Fluids: Both strongly resist common automotive fluids, ensuring lasting seals in various vehicle systems.
What’s better about Threebond 1104?
• Flexibility: After curing, 1104 remains more flexible, making it ideal for applications where components might move or vibrate.
• Low-Pressure Applications: Its composition makes it particularly effective in sealing areas where pressure is not exceedingly high.
• Ease of Removal: When it’s time for disassembly or repairs, 1104 can be removed more efficiently than the more challenging 1184.
• Sensitive Applications: Its gentle nature makes it suitable for less robust materials or components that a stronger sealant might damage.
What’s better about Threebond 1184?
• High-Temperature Resistance: 1184 excels in environments exposed to high temperatures, maintaining its integrity where 1104 might falter.
• Chemical Resistance: Its robust formulation protects against aggressive chemicals and oils.
• High-Pressure Environments: 1184’s strength makes it suitable for applications where pressure is a significant factor, ensuring seals remain intact under stress.
• Longevity: In demanding conditions, 1184 tends to hold up longer, providing a durable bond that resists wear and tear.
Who should get Threebond 1104 (and why)?
Threebond 1104 is ideal for hobbyists, mechanics, and technicians who deal with low-pressure systems, flexible components, or sensitive materials.
Its forgiving nature and flexibility make it suitable for a broad range of applications, particularly where a gentle yet effective seal is necessary.
If you’re working on light engines or delicate electronics or need a reliable sealant that won’t stress the materials it’s applied to, 1104 is your go-to.
Who should get Threebond 1184 (and why)?
Threebond 1184 is the choice for those in high-temperature, high-pressure, or chemically aggressive environments.
1184 suits mechanics working on heavy-duty engines, industrial machines, or components subjected to harsh conditions.
If your work demands a maximum resistance and durability sealant, 1184 stands ready to meet the challenge.
Threebond 1104 Vs. 1184: A Recap
To choose between Threebond 1104 and 1184, you need to consider the specific requirements of your project.
Due to its ease of use, Threebond 1104 is ideal for flexible, low-pressure applications, while 1184 excels at withstanding high temperatures and pressures and offers durability against chemicals and wear.
Choose based on your work’s needs, the sealant’s operating conditions, and the desired durability. Both products reflect Threebond’s dedication to quality and reliability, catering to different but essential sealing needs.
