The Ultimate Guide to Dispensing Tips

Angled Tips are indispensable in scenarios where components create deep shadows or tight spaces on a board. In electronics manufacturing, they allow for precise adhesive deposition around tall connectors or under shielded components without requiring tooling changes. The automotive industry leverages them to apply sealants and lubricants into multi-layered assembly gaps. By delivering material directly to the target area, they not only accelerate production cycles but also significantly lower the risk of costly overspray and cross-contamination, ensuring a cleaner and more reliable assembly line.

Blunt Tip Needles are the go-to choice for a wide range of industrial and laboratory applications when safety and accuracy are top priorities. These needles feature a rounded, non-sharp tip that prevents accidental punctures and protects sensitive substrates from damage. 

Blunt needles are highly versatile and seamlessly compatible with syringe cartridges, valves, and mixing tubes, allowing for easy integration into both manual and automated systems. Available in a variety of materials, these precision-engineered components are suitable for applying adhesives, solvents, lubricants, inks, and other liquids.

Key Advantages of Blunt Tip Needle

• Safe design with rounded, non-sharp tip prevents damage and injury
• Broad material compatibility for adhesives, solvents, lubricants, and inks
• Available in multiple gauges and lengths to meet diverse application needs

Brush Dispensing Tips excel in transforming a simple dispensing action into a precise coating process. In precision electronics assembly, the gentle bristles safely apply lubricants or fluxes onto sensitive connectors and PCB surfaces, preventing scratches while guaranteeing a uniform film thickness. For automotive maintenance and repair, the robust bristle structure is ideal for applying protective coatings or sealants onto irregular metal or composite parts, ensuring complete coverage in tough environments. This capability to combine fluid placement with immediate spreading significantly reduces material waste, improves finish quality, and boosts efficiency in both manual and automated workflows.

Flexible Dispensing Tips are the ideal solution for achieving precision in confined spaces and on sensitive surfaces where rigid needles pose a risk. Engineered from high-quality polypropylene (PP), these tips can be easily bent and maneuvered around obstacles, ensuring accurate fluid placement in tight or angled areas without causing surface damage.

Btektech offers both glue-bonded for general use and one-piece integrated (P-Series) with chemical resistance for harsher fluids. Their inherent flexibility and ability to be trimmed to the exact required length make them uniquely adaptable to complex dispensing challenges.

These tips excel in situations where a rigid tool would be impractical or damaging. In PCB assembly, they safely navigate around fragile components and tall connectors to dispense flux or UV adhesives, preventing costly damage and rework. For medical device and lab equipment assembly, the flexible body allows for precise micro-volume dispensing of lubricants onto intricate, curved plastic parts, ensuring complete coverage without contamination. By providing a safe and adaptable way to reach deep grooves or hidden channels, they enhance process reliability and protect product integrity across advanced manufacturing lines.

When your application requires a flat, consistent bead of high-viscosity material rather than a traditional round dot, Oval Dispensing Tips are the ideal solution. Precision-engineered with an elongated oval orifice, these tips deposit a smooth, flat ribbon of pastes, gels, and sealants, ensuring uniform coverage over broader bonding areas in a single pass.

Btektech offers these tips in both a cost-effective Polypropylene (PP) Hub with stainless steel needle and a fully metal construction with riveted joint for superior strength. For specialized needs, our standard needles can also be custom-machined into oval versions to meet unique application requirements.

· Flat ribbon output for wide, consistent coverage of thick fluids

· PP and all-metal options for different strength and cost needs

· Custom-machinable from standard needles for specialized tasks

The unique flat bead profile of oval tips is a game-changer for applications where area coverage is more critical than a dot or line. In electronics, they are perfect for efficiently spreading thermal interface materials or gap fillers across large components, enhancing heat dissipation without air gaps. Within industrial equipment assembly, the oval orifice enables the precise deposition of lubricants and heavy-duty sealants in a flat pattern onto gears and fasteners, ensuring complete coverage that reduces wear and prevents loosening. This capability to form a uniform, wide bead in one step significantly accelerates production, minimizes material waste, and guarantees a more reliable bond or seal.

PTFE-lined Dispensing Tips are engineered to excel in the most challenging chemical environments, setting the benchmark for clog-resistant performance and precision. The unique design integrates a stainless steel outer cannula with an inner smooth PTFE lining that extends approximately 3mm beyond the needle, forming a dedicated non-stick outlet zone.

This construction is specifically optimized for low-viscosity, reactive fluids like cyanoacrylates (instant adhesives) and anaerobics, which are prone to curing upon contact with metal surfaces. The result is unparalleled anti-clogging performance and consistent, reliable fluid dispensing.

PTFE tips are indispensable in automated and high-volume settings where downtime for clearing clogs is costly. In electronics micro-assembly, they enable the continuous and precise application of instant adhesives for component bonding without the risk of tip blockage disrupting production cycles. The automotive industry leverages them for applying sealants and adhesives on sensors and connectors, where the chemical resistance ensures fluid integrity and prevents contamination of critical parts. By guaranteeing a stable, predictable flow of even the most reactive chemicals, these tips enhance bonding quality, reduce waste, and uphold throughput in professional manufacturing workflows.

Stainless Steel Dispensing Tips represent the premium standard for strength and precision in demanding fluid dispensing. Featuring precision-machined, burr-free stainless steel needles combined with a nickel-plated brass hub and secure Luer lock, these tips are engineered for unwavering reliability in high-speed automated production.

The full-metal, riveted construction provides exceptional mechanical strength and temperature resistance, ensuring dimensional stability and precise needle alignment even under high pressure. This makes them ideal for dispensing a wide range of demanding fluids, from adhesives and solvents to oils and activators.

· Premium burr-free needles for consistent flow and dot placement

· High strength & temperature resistance with riveted metal construction

· Precise flow control for demanding fluids in automated systems

Stainless Steel Dispensing Tips are used across a wide range of industries. In electronics assembly, their metal-on-metal design prevents interaction with sensitive substrates, ensuring pure, contamination-free application of adhesives and chemicals in SMT and PCB repair processes. The automotive sector relies on them for their resilience against harsh chemicals like activators and anaerobic adhesives, providing consistent performance in dynamic, high-temperature bonding and sealing operations. For industrial automation, their riveted design guarantees stable needle alignment and unwavering flow accuracy, which is critical for maintaining uptime and precision in robotic dispensing systems. This combination of ruggedness and precision directly translates to reduced downtime and enhanced process reliability in high-volume manufacturing.
