Mil-spec wire, cable, and fire protection — sourced to spec, certified, delivered.

01 Why buy from Williwaw
Defense-grade sourcing discipline, applied to whatever you need built or supplied.
We make hard-to-source material low-risk to buy. The same mil-spec and high-temperature constructions that hold up in defense work serve demanding commercial, medical, and industrial jobs just as well. Because we buy direct from approved manufacturers, the right part arrives the first time, with the traceability paperwork already in hand. No brokered surplus, no receiving-inspection surprises, no minimum-order runaround.
- Hard-to-source material — long-lead and low-volume items others won’t chase
- Proven in medical, industrial & aerospace — sensitive signal, sensor, and MRO cable
- Passes receiving inspection — approved-source only, traceable to the lot
- Verified revision levels — the current spec, not last year’s
- Straight answers, fast — direct manufacturer ties mean real lead times and revisions
- You reach the owners — a small team, not a ticket queue
02 Capability areas
A deliberately narrow line, built around two specialties: high-performance wire and cable, and fire, thermal, and safety solutions.
Mil-spec wire
M22759, M16878, and M5086/2 military power cable — engine and airframe applications, manufactured to the latest revision.
Mil-spec cable
M27500, M27600, M55021, and M27027 constructions, shielded and jacketed to NEMA WC27500.
Extreme environment
200°C to 450°C FEP, TFE, PFA, TGGT and MGT. High-temperature thermocouple cable to M5846 and M5908.
TEMPROTEX® coatings
Intumescent fire-extinguishing coating that stops liquid fire on contact. SFI 54.1 approved, ASTM E84 Class A.
Firestable™ FS 2.0
NFPA-275 certified all-in-one thermal barrier SPF insulation — code compliant the moment it is applied.
Built-to-print cable
Multi-conductor shielded and jacketed cable for medical instrumentation, industrial sensors, and audio systems.
03 How we work
From requirement to delivered, certified material — with one point of contact the whole way.
-
Identification
Evaluate the requirement against approved sources. For government orders that means confirming the manufacturer is QPL/QML-approved for the NSN before we quote.
-
Introduction
Connect the customer to the right manufacturer and construction — including novel technologies that solve the requirement better than the incumbent part.
-
Integration
Support integration and implementation of the material, tailored to the application — continuous lengths, spool configuration, marking, and packaging to spec.
-
Distribution & support
Single point of contact through delivery. Certificate of Conformance, lot and date code traceability, and quality records available on request.
