INTRODUCTION

Structure Description:

The main material of the steel sleeve press fittings is brass, and the O-ring material is EPDM rubber. Structurally, each fitting is equipped with two O-rings that function as dual seals after installation. When thermal expansion or cold contraction occurs between the pipe and the fitting nipple, the O-rings automatically rebound and reseal to prevent leakage. Additionally, the stainless steel sleeve plug surface features three grooves, which form a wave structure after being compressed by the tool. This design ensures highly reliable sealing performance.

Technical Parameters:

Main Components: Brass body , 304 stainless steel sleeve, PE seat, EPDM O-ring;

Working Pressure:≤1.0MPa

Medium: Oil,water,gas

Working Temperature: -10℃ to +95℃

Characteristics:

1. Stable Installation

Traditional compression fittings rely on threaded connections, which are prone to loosening and require regular maintenance. In contrast, the new press fittings utilize a press tool for assembly. Once installed, no further maintenance is required, ensuring long-term structural integrity.

2. Cost-Effectiveness

By replacing brass hex nuts with 304 stainless steel sleeves, material costs are reduced by approximately 30% while maintaining durability. This design optimizes both initial investment and lifecycle expenses.

3. Additional Features

- Corrosion Resistance: Certified to withstand aggressive media (pH 4-10), with a service life exceeding 50 years (per ASTM B117 salt spray test).

- Health Compliance: Meets NSF/ANSI 61 standards for drinking water safety.

- High-Rise Adaptability: Engineered for high-pressure stability (≤1.6 MPa), suitable for vertical pipe systems in skyscrapers.

- Installation Efficiency: Compatible with ergonomic press tools (e.g., hydraulic or battery-operated), enabling rapid connections in confined spaces.
