I. Product Overview

This insulation resistance component uses aluminum alloy CNC precision turned multi-step stepped metal ends, with a glass fiber insulation isolation rod in the middle, featuring an integrated sealing groove structure for installing O-rings. The glass fiber material effectively achieves electrical isolation between the two poles, with excellent pressure resistance and insulation properties; the sealing structure blocks the penetration of liquids and media, the front stepped guide head facilitates assembly and insertion, and is widely used in internal electrical isolation of fluid control and high-voltage sensing equipment.

Supports various metal materials such as aluminum alloy, stainless steel, and brass; outer diameter, stepped layout, insulating rod length, and sealing groove size can be customized according to customer drawings or physical samples; supports small batch trial production and long-term large batch supply; finished products undergo strict inspections for insulation performance and assembly dimensions.

Section Two: Core Highlights of Craftsmanship and Workmanship

1. Aluminum alloy end piece, CNC integrated turning, multi-step stepped forming in one operation
   Guided cone head, limit step, and sealed card slot are all cut as a whole, no need for secondary processing, high dimensional accuracy, and good batch interchangeability.
2. Fiberglass core rod with insulation and electrical insulation, pressure-resistant and leakage-proof
   The intermediate glass fiber insulated rod physically isolates the two poles with conductive ends, effectively enhancing the voltage withstand level, preventing circuit short-circuits and leakage faults, and suitable for high-voltage conditions.
3. Integrated seal groove structure for medium sealing and protection
   Precision machined annular seal groove, O-ring assembly fits tightly, preventing oil and moisture from seeping into the component interior, extending service life.
4. Compression assembly technology, shockproof and anti-loosening
   The metal end and glass fiber rod are precision fitted together, which is not easy to separate or crack under continuous vibration working conditions, ensuring a long-term stable insulation structure.
