Product Name
Jensen Tapered-Tip 20-Gauge Dispensing Tips (Push-On & Luer-Lock) -1.25-inch
Brief Description
These Jensen Tapered-Tip 20-Gauge Dispensing Tips are precision tools designed for the controlled and accurate application of various fluids, particularly medium to high viscosity materials and those with particles. The tapered design facilitates smooth, consistent flow and reduces back pressure, preventing clogging and stringing. Available with both push-on and Luer-Lock connections, these 1.25-inch tips offer versatility and secure attachment to a wide range of dispensing systems.
Popular Applications & Uses
- Applying adhesives, epoxies, and sealants- Dispensing solder paste and flux in electronics assembly and rework- Precision lubrication and greasing- Gasketing and potting applications- Handling minute volumes of liquids in laboratory and scientific research- Craft and hobby applications, such as applying paint or glue- Dispensing compounds, gels, and RTVs- Applying UV-cure materials and cyanoacrylates
Industries that Commonly Use It
- Aerospace/Defense (for precision bonding and sealants)- Artist, Artisan (for intricate work with paints and glues)- Automotive Service/Repair (for lubricants and sealants)- Chemical Industry (for precise application of various chemicals and solvents)- Distributers & Resellers (as a common industrial supply product)- Engineering Services (for prototyping and R&D requiring precise fluid application)- General Manufacturing (for assembly fluids, adhesives, and sealants across various products)- LED/Electronics (for solder paste, epoxies, and rework on sensitive components)- Medical Device/ Prosthetics (for precision bonding and sealants)- Metal Fabrication (for applying adhesives and sealants)- Mold Making/ Casting (for dispensing resins and epoxies)- Plastic Fabrication (for applying adhesives and sealants)- Prosumer (for DIYers and hobbyists requiring industrial-grade precision)
Special and Unique Features
- **Tapered Design:** Engineered to reduce back pressure, prevent clogging, and ensure a smooth, consistent flow, especially with viscous or particle-filled materials.- **Dual Connection Options:** Features both push-on and Luer-Lock compatibility for broad versatility with different dispensing syringes and valves.- **20-Gauge Opening:** Provides a controlled dispensing rate suitable for a wide range of applications.- **1.25-inch Length:** Standardized length for reaching specific application areas.- **Scratch-Free Protection:** Ideal for working with sensitive parts, as the plastic tip prevents surface damage.- **Industrial Grade:** Certified for industrial use, often silicone-free and safe for high pressures (e.g., up to 100 psi).
Key Properties
- **Material:** Typically high-density molded polypropylene or polyethylene, often with UV-light block additives for light-sensitive fluids.- **Gauge Size:** 20-gauge (internal diameter approximately 0.023-0.025 inches or 0.58-0.64 mm).- **Length:** 1.25 inches (approximately 31.75 mm).- **Tip Type:** Tapered, blunt end.- **Connection Type:** Push-on and Luer-Lock (double-helix thread for secure attachment).- **Fluid Viscosity Suitability:** Best for medium to high viscosity fluids, pastes, gels, and particle-filled materials.
Surface Compatibility
- The tips themselves are generally inert plastic (polypropylene/polyethylene) and are compatible with most surfaces as they primarily serve to deliver the fluid.- The compatibility with the actual work surface depends on the chemical properties of the dispensed fluid (adhesives, solvents, etc.) and the substrate material.- Designed for scratch-free application, making them suitable for sensitive parts.
Known backups / known substitutes
- **Other Gauge Dispensing Tips:** Different gauge sizes (e.g., 18-gauge for faster flow, 22-gauge for finer control) for varying flow rates and deposit sizes.- **Straight Wall Dispensing Tips:** Standard blunt end metal or plastic tips, suitable for a wider range of viscosities but may not offer the same clog resistance for high-viscosity or particle-filled materials.- **Metal Dispensing Tips:** Stainless steel tips, often with nickel-plated brass hubs, offering higher precision, durability, chemical resistance, and suitability for aggressive solvents or high-pressure applications.- **Flexible Polypropylene Tips:** For reaching difficult areas or preventing scratching on delicate surfaces.- **Angled Dispensing Tips:** For precision dispensing in hard-to-reach or confined areas.- **Brush Tips:** For spreading, marking, or coating applications.- **PTFE-Lined Tips:** Ideal for low-viscosity fluids, solvents, and cyanoacrylates to prevent clogging and wicking.
Comparison Note
Tapered dispensing tips, like the Jensen 20-gauge model, are specifically engineered to provide a smoother, more consistent flow for medium to high viscosity fluids and particle-filled materials compared to straight-wall tips of the same gauge. Their design reduces back pressure and minimizes clogging, leading to improved yields and reduced rework. The inclusion of both push-on and Luer-Lock connections offers superior versatility and a more secure, leak-free attachment, with Luer-Lock being particularly robust against accidental disconnections under pressure. While metal tips offer greater durability and chemical resistance for aggressive fluids, plastic tapered tips provide scratch-free protection for sensitive substrates.
