PVA 3-16"Od Uv Safe, Black Teflon Material Line, Material Line And (Typical Use)
PVA TFETB01250187B — 3/16" OD UV-Safe Black PTFE (Teflon) Material Line
The PVA TFETB01250187B (SKU: TFETB01250187B) is a 3/16" OD UV-safe black PTFE (Teflon) fluid material line for use in PVA fluid dispensing systems. The black PTFE construction provides UV protection for light-sensitive dispensing materials — including UV-cure adhesives, conformal coatings, and other photosensitive fluids — preventing premature curing in the fluid line during dispensing operations. PTFE offers excellent chemical resistance to a broad range of solvents, adhesives, fluxes, and coatings used in electronics assembly.

Key Features
- UV-safe black PTFE — black pigment blocks UV light, preventing premature curing of UV-cure adhesives and photosensitive coatings in the fluid line
- PTFE (Teflon) construction — excellent chemical resistance to virtually all solvents, adhesives, fluxes, and coatings used in electronics assembly dispensing
- 3/16" OD — standard PVA material line diameter for compatibility with PVA dispensing system fluid circuits
- Flexible and kink-resistant — PTFE tubing maintains flow path integrity in routed dispensing system installations
- Low friction inner surface — PTFE’s non-stick surface minimizes fluid adhesion and residue buildup inside the line
Frequently Asked Questions
Why is UV-safe black tubing needed for dispensing UV-cure materials?
UV-cure adhesives and conformal coatings cure when exposed to UV light. If standard clear or translucent tubing is used, ambient UV light (from overhead lighting, sunlight, or nearby UV lamps) can penetrate the tubing wall and begin curing the fluid inside the line — causing blockages, inconsistent viscosity, and dispensing failures. Black PTFE tubing blocks UV light completely, keeping the fluid in its uncured state until it is dispensed and intentionally exposed to the UV cure lamp.
What fluids is PTFE (Teflon) tubing compatible with?
PTFE has one of the broadest chemical resistance profiles of any tubing material — it is compatible with virtually all solvents, acids, bases, adhesives, fluxes, conformal coatings, and cleaning agents used in electronics assembly. This makes it the preferred material line for PVA dispensing systems handling aggressive or reactive fluids. Refer to a PTFE chemical compatibility chart for your specific fluid if needed.
Is this tubing specific to PVA dispensing systems?
This tubing is designed and specified for use as a material line in PVA fluid dispensing systems, where it connects the fluid reservoir to the dispensing valve. It may also be compatible with other dispensing systems using standard 3/16" OD tubing fittings. Contact MTE Solutions to confirm compatibility with your specific dispensing system.
How is the material line replaced or cut to length?
PTFE tubing can be cut to length with a sharp tubing cutter or razor blade for a clean, square cut. Ensure the cut end is clean and free of burrs before connecting to fittings. Contact MTE Solutions for compatible fittings, connectors, and installation guidance for PVA dispensing systems.
