MIL-W-16878/20 PTFE Tape-Wrapped Hook-Up Wire Mil-Spec 250V Aerospace Wire

Product Overview

When your project demands reliability under extreme conditions, the MIL-W-16878/20 delivers. This PTFE tape-wrapped hook-up wire is built to MIL-W-16878/20 and NEMA HP-3 TYPE ET standards, using a silver-plated copper stranded conductor with tape-wrapped PTFE insulation — giving you a thinner wall, smaller outer diameter, and lighter weight than extruded alternatives.

Rated for 250V AC and continuous operation from -60°C to +200°C, it's engineered for environments where space is tight and performance can't be compromised.

Key Features and Benefits

Survives the heat: Continuous 200°C operation, short-term up to 300°C. PTFE insulation is self-extinguishing and won't melt or drip in flame.

Bends without breaking: The tape-wrapped construction flexes more easily than extruded insulation, making routing in cramped panels far less frustrating.

Chemically bulletproof: Resists acids, alkalis, solvents, moisture, UV — virtually inert in harsh environments.

Solder-friendly: High soldering iron temps won't shrink or melt the insulation, so terminations stay clean and reliable.

Lighter, leaner wiring: Thin-wall design means less bulk and lower weight per meter — a big deal in aerospace and portable gear.

Frequently Asked Questions (FAQ)

Q: How does M16878/20 compare to M16878/4?

A: The /20 type uses tape-wrapped PTFE insulation with a thin wall, while /4 uses extruded PTFE with a medium wall. The /20 is the lightest and most flexible option in the MIL-W-16878 series.

Q: Can M16878/20 be used for wire-wrap (solderless) terminations?

A: Yes, the tape-wrapped construction and stranded conductor make M16878/20 suitable for wire-wrap applications. However, automatic high-speed stripping can be more challenging with thin-wall tape-wrapped PTFE, especially on finer gauges.

Q: What conductor materials are available for M16878/20?

A: Silver-plated copper is the standard conductor per the MIL-W-16878/20 specification. Special conductors such as nickel-plated copper, stainless steel strands, or high-strength copper alloys may be available for custom orders.

Q: Is M16878/20 suitable for outdoor or UV-exposed applications?

A: Yes. PTFE is highly resistant to UV radiation, ozone, and weathering. It does not absorb moisture and remains stable in outdoor environments, making M16878/20 a reliable choice for exposed installations.

Q: What is the minimum bend radius for M16878/20 wire?

A: The tape-wrapped PTFE construction provides superior flexibility compared to extruded alternatives. While the exact minimum bend radius depends on AWG size, M16878/20 can typically be bent to a radius of 2–3 times its outer diameter without damage.

Q: What's the typical lead time?

A: Standard sizes and colors are often in stock for quick shipment. Custom orders typically take 2–4 weeks depending on quantity and specifications. Contact us for current availability.
