Key Features
- Genuine OEM Thread Specification — Manufactured to Husqvarna's exact 3/8 thread standard, ensuring correct torque engagement and a secure tube connection without risk of thread mismatch or fitting failure.
- Direct Drop-In Replacement — Engineered to seat precisely in the same tube connection point as the original, allowing straightforward installation without modification to surrounding fittings or hardware.
- Designed for the HTC400 Floor Grinder — Verified OEM fitment for the HTC400, one of Husqvarna's professional-grade planetary floor grinders used in surface preparation and concrete polishing applications.
- Maintains a Secure Fluid or Air Path — A correctly fitted tube connection nut prevents loosening under machine vibration, protecting the integrity of the connected system and preventing fluid or pressure loss during operation.
- Husqvarna OEM Quality Assurance — Sourced directly through the Husqvarna OEM parts channel, this nut meets the same material and dimensional standards as the part originally installed at the factory.
A tube connection nut secures the fitting where a fluid or pneumatic line meets a port or manifold within the machine. When properly tightened, it creates a reliable, vibration-resistant seal that keeps the connected system pressurized and free of leaks. A worn, damaged, or improperly seated nut can cause pressure loss, fluid seepage, or fitting movement that compromises the performance of the system it supports — making correct replacement critical to restoring full machine function.
