Self-wrapping Sleeve ROUNDIT® 2000 NX & ROUNDIT® 2000 NX HT

The high-performance protection solution for your aerospace wiring harnesses

At Air Cost Control, we share the aircraft manufacturers’ obsession: every gram taken aloft affects payload, fuel burn, and ultimately operating profitability. Yet while lightness is critical, reliability is just as vital—a single harness defect can ground an aircraft, drive sky-high AOG costs, and derail the entire flight rotation.Mindful of this delicate balance, we chose the ROUNDIT® 2000 NX range to give your teams a protection system that compromises neither weight, durability, nor quality. It offers the ideal blend of strategic lightness, proven robustness, instant installation, and comprehensive safety, all backed by Air Cost Control’s logistics support.

Why choose ROUNDIT®?

Quick installation and removal, even on the flight line

• Thanks to its self-wrapping design, ROUNDIT® 2000 NX opens with a simple press of the thumb, like a reverse hook-and-loop fastener. Release it and the fibres snap back into place, instantly forming a smooth, uniform sleeve with no gaps or snag points. In practical terms, your technicians can isolate or rework an entire harness without disconnecting a single connector or removing neighbouring parts. In an MRO shop that means shorter aircraft downtime; on the assembly line it keeps the build rate flowing and reduces the time bare cables are exposed.

An ultra-light mechanical barrier

• The secret lies in its flat subtstrate, woven—depending on the version—from Nomex®, PPS, or PEEK monofilaments. Once closed, the product becomes a continuous tube that resists cuts, shear, and abrasion while weighing only a few grams per metre. Scaled to a long-range jet or a full helicopter, that mass saving adds up to kilos off the airframe and therefore lower fuel burn, without any compromise on harness toughness.

Halogen-free, water-repellent, and built to last

• Free of halogens, the sleeve emits no corrosive smoke in the event of fire, meeting FAR Part 25 fire-safety requirements and ASD EN 6049 specifications. A hydrophobic treatment prevents moisture absorption, so condensation can’t creep between conductors, even through extreme hot/cold cycles or humid stopovers. The result: preserved electrical insulation, reduced corrosion risk, and a longer harness service life—from first flight rotation to the aircraft’s retirement.

Two variants to cover the entire temperature spectrum

ROUNDIT® 2000 NX

• Woven from a high-performance Nomex® / PPS duo, this sleeve shrugs off thermal shocks from -60 °C to +200 °C. Its textile look keeps a premium appearance, ideal for visible areas such as seat or overhead-bin harnesses, while delivering genuine mechanical protection against abrasion and shear. Ultra-lightweight, it adds minimal mass and helps cut fuel burn, a decisive benefit for every commercial or military operator.

ROUNDIT® 2000 NX HT

• In compartments where temperatures push +260 °C (≈ 500 °F), the HT version swaps PPS for high-modulus PEEK. An ivory tracer runs the full length, signalling at a glance that it is qualified for high temperatures. Rated from -70 °C to +260 °C, it also boosts resistance to arcing and flashover, making it the natural choice for engine harnesses, power cables, or HV lines routed near hot spots. Of course, it remains self-wrapping, halogen-free, and fully compliant with FAR Part 25 and EN 6049-007 fire/smoke requirements, guaranteeing safety and simplified maintenance throughout the aircraft’s life cycle.

The Air Cost Control advantage

• Stock on hand at our European and U.S. hubs to keep your programmes on track.
• Kitting & labelling to match your wiring plans—each sleeve arrives ready for immediate installation.
• Technical support for diameter selection and standards qualification (ASD EN 6049-006/007, BMS 13-81, DMS 2379, and more).
• 24/7 AOG service for your fleet emergencies.
