ASTM D2467 is a crucial standard specification that defines the requirements for poly(vinyl chloride) (PVC) plastic Schedule 80 pipe fittings. These fittings are specifically designed for demanding applications involving the distribution of pressurized liquids, ensuring both safety and long-term reliability.
Understanding the Scope of D2467
This comprehensive specification outlines stringent criteria that these fittings must meet to ensure optimal performance and compatibility within various systems. It covers critical aspects from the fundamental composition to the final performance characteristics.
Key Requirements Covered by ASTM D2467
The standard dictates specific requirements for several vital areas of PVC Schedule 80 fittings:
- Materials: Specifies the type and quality of poly(vinyl chloride) (PVC) compounds used, ensuring they possess the necessary chemical resistance and mechanical strength.
- Workmanship: Details the quality of manufacturing processes, including molding and finishing, to ensure fittings are free from defects that could compromise their integrity.
- Dimensions: Sets precise dimensional tolerances for various fitting types (e.g., elbows, tees, couplings) to guarantee proper fit and interchangeability with Schedule 80 PVC pipe.
- Burst Pressure: Establishes minimum burst pressure ratings, which is a critical safety measure, verifying that the fittings can withstand the specified internal pressures without failure.
- Intended Use: Clearly states that these fittings are for use with the distribution of pressurized liquids that are chemically compatible with the piping materials, highlighting their suitability for industrial and chemical processing environments.
Why Schedule 80 PVC Fittings?
Schedule 80 PVC fittings are distinguished by their thicker walls compared to Schedule 40 PVC, which makes them inherently more robust. This increased wall thickness provides:
- Higher Pressure Ratings: Essential for applications where systems operate under elevated pressures.
- Enhanced Durability: Greater resistance to impact and abrasion, contributing to a longer service life.
- Broader Temperature Range: While PVC has temperature limitations, Schedule 80 fittings often perform better at the higher end of PVC's recommended temperature range.

Applications and Importance
ASTM D2467 compliant fittings are indispensable in a wide array of industrial and commercial applications where strength and chemical resistance are paramount. Common uses include:
- Chemical Processing: Transporting corrosive chemicals safely.
- Industrial Water Treatment: Handling high-pressure water systems and aggressive chemical solutions.
- Waste Treatment Plants: Durable piping for demanding environments.
- Heavy-Duty Irrigation: Systems requiring robust components to withstand pressure and environmental factors.
- Manufacturing Facilities: Various process piping needs for liquids.
Adherence to ASTM D2467 ensures that fittings from different manufacturers will meet consistent performance and quality benchmarks, promoting safety, reliability, and ease of system design.
Benefits of Using D2467 Compliant Fittings
Choosing fittings that meet the ASTM D2467 standard offers numerous advantages:
- Assured Quality: Guarantees that the fittings have undergone rigorous testing and meet specified material and performance criteria.
- System Integrity: Reduces the risk of leaks, bursts, and failures, protecting personnel and property.
- Interchangeability: Ensures that fittings from various suppliers will be dimensionally consistent and compatible with Schedule 80 PVC pipe.
- Longevity: Contributes to the overall lifespan of piping systems due to superior strength and durability.
- Regulatory Compliance: Helps meet industry standards and often local building codes for pressurized liquid systems.
