Wacker Neuson 5000173256 1 NPT Strain Relief 0.59–1.0

The Wacker Neuson is a genuine OEM 1 NPT Strain Relief 0.59–1.0 designed for the HI260, HI750, HI900, and HI1000 indirect air heater series, as well as E5000 ground heaters. As a genuine Wacker Neuson part, the is manufactured to the exact dimensions and material grade specified for these machines, ensuring a correct, secure fit with no guesswork on sizing or compatibility. This strain relief is engineered to accept cable or conduit diameters in the 0.59 to 1.0 inch range, making it the right choice for the specific wiring configurations found across the HI and E5000 heater families. Confirmed fitment spans multiple configurations including diesel, gas, DGM, surge brake, and electric brake variants across the HI1000, HI900, HI750, HI260, and E5000 series.

Key Features

• Genuine OEM Construction: — Manufactured to Wacker Neuson's specified material grade and thread tolerances for a 1 NPT fitting, ensuring the grip and strain distribution function exactly as intended for heater electrical connections.
• Correct Cable Range: — Sized to accept cables and conduit from 0.59 to 1.0 inches in diameter, matching the wiring harness dimensions found in HI and E5000 series heater assemblies.
• Drop-In Replacement: — Threads directly into the existing 1 NPT port with no additional adapters or modifications to the heater enclosure or wiring entry point.
• Broad Heater Compatibility: — Fits HI260, HI750 DGM, HI900 DGM, HI1000, and E5000 ground heaters across diesel, gas, surge brake, and electric brake configurations.
• Electrical Safety Function: — A properly seated strain relief prevents cable movement at the entry point, protecting wire insulation and internal connections from abrasion, pull-out, and vibration damage — critical on mobile heating equipment.

A strain relief is a clamping fitting installed at the point where an electrical cable enters an enclosure or housing. Its job is to grip the cable firmly so that any tension, pulling force, or vibration acting on the cable is absorbed by the fitting rather than transferred to the internal wiring terminations. On indirect air heaters and ground heaters like the HI and E5000 series — equipment that is regularly transported between jobsites — cable connections are exposed to constant movement and vibration. A worn, cracked, or missing strain relief allows the cable to shift at the entry point, which over time can damage insulation, loosen terminals, and create an electrical fault. Replacing a damaged unit with the correct Wacker Neuson 5000173256 restores the mechanical protection the wiring system depends on.
