I. Product Overview

This T-type metal sleeve is precision-machined from metal tube stock, forming a verticalinterconnection T-shaped through-hole structure; the outer surface of the sleeve is integrally machined with straight ribbed knurling texture, which, after being pressed and embedded into the housing and plastic interior, ensures a firm fit and effectively prevents rotation and slippage after assembly. The entire product can be treated with surfaceCorrosion prevention processes such as chrome plating and galvanizing, with smooth and burr-free inner and outer holes, and the rods and pipelines can be assembled smoothly.
Support customization for various raw materials including carbon steel, stainless steel, brass, and aluminum alloy, with adjustable cylinder dimensions, hole sizes, branch lengths, and knurling ranges as per drawings or physical samples; capable of handling small batch trials and long-term large-scale supply, with the entire production process adhering to ISO9001 quality standard inspections.

Part Two: Core Highlights of Craftsmanship

1. Pipe CNC integrated turning and drilling, T-type interconnect structure is regular
   Seamless tube materials are precision machined and shaped. The main cylinder is vertically connected to the lateral branch tube, with good concentricity of hole positions, uniform wall thickness, and high pressure resistance without deformation; without secondary welding joints, offering higher structural strength.
2. One-step processing of exterior straight-rib embossed surface, pressure-fitted and non-slip without loosening
   The cylindrical surface features evenly distributed embossed textures, which, after being pressed into the plastic or metal base, increases the frictional force of the contact surface. Long-term use will not cause circumferential rotation or axial loosening, ensuring strong stability.
3. Port-wide deburring treatment, assembly without damaging the workpiece
   All internal and external hole edges, pipe openings are fully deburred and smoothed, ensuring no scratching during the insertion of shafts and pipelines, resulting in smooth and efficient assembly.
4. Chrome-plated anti-corrosion surface, bright, wear-resistant and rust-proof
   Regular style with surface chrome plating, dense and glossy, wear and corrosion resistant, long-term use in indoor and mild humid environments is not easy to rust.

Section 3: Optional Customizable Raw Materials

1. Low-carbon Steel Pipe (Recommended)
   Easy to machine, suitable for knurling, high cost-performance ratio, the preferred choice for furniture and general equipment fasteners.
2. 304 Stainless Steel
   Excellent rust-proof performance, specially designed for outdoor, humid, and water-exposed conditions.
3. Brass
   Good conductive performance, suitable for electrical and electronic module conductive connection bushes.
4. Aluminum alloy
   Lightweight, suitable for weight reduction accessories for light instruments and small equipment.

Chapter 7: Common Procurement Q&A

Q1: Can the hole diameter and length dimensions be modified according to the sample or CAD drawing?
A: Sure, we can receive drawing measurements or a one-to-one replica of the physical item, adjusting allAppearance parameters as required.
Q2: Can we make the plain finish without knurling?
A: Support is available for smooth cylindrical, straight ribbed, and cross ribbed options as per requirement.
Q3: For water conveyance conditions, which material and surface treatment are recommended?
A: Prefer 304 stainless steel, no need for electroplating, with the best rust and water resistance.
Q4: Can the through-hole angle not be made into a 90-degree right angle?
Customizable three-way sleeve with any intersecting angle, supporting non-standard angle processing.
Q5: What is the minimum inner diameter specification available?
A: The miniature tee bushings with micro apertures support customization according to pipe specifications.
