Double Containment Termination Fittings

Double containment termination fittings are used to create a transition point for starting or stopping a secondary containment piping system. The fittings feature a closed outer containment pipe and a central internal coupling that allows continuation of the internal carrier pipe to equipment or an existing system. Termination fittings securely join the carrier and containment pipes at the endpoints of double containment systems, integrating both pipes into a single, leakproof unit. Double containment (DC) termination fittings finalize dual pipe systems and effectively maintain a secure, closed system for transporting hazardous, corrosive, or sensitive fluid without risk of leaks or critical release. DC termination fittings are primarily used in industries where release of transported fluids could pose significant environmental, health, or safety hazards. Examples include chemical processing plants, water treatment facilities, and pharmaceutical manufacturing.

Double containment termination fitting sizes range from 1/2ʺ x 2ʺ up to 8ʺ x 12ʺ in carrier pipe by containment pipe measurements. Additional sizes are available on request. DC termination fittings come in SCH 40, SCH 80, and combination SCH 40 x SCH 80 thickness standards. Double containment termination fittings come with a reducer coupling for containment pipe connections and an internal extender coupling for carrier pipe connections in slip on socket joint configuration. Internal couplings come with an extender to facilitate connections between carrier pipe sections. Solvent weld installation with primer and cement is recommended. DC termination fittings can be used with standard, dual layer, or clear PVC and CPVC pipe. 

Our double containment termination fittings are USA made by Spears Manufacturing®. Spears® is a trusted, top choice manufacturer with decades of experience in providing professional grade pipe products. DC termination fittings are fabricated from industrial strength polyvinyl chloride (PVC) or chlorinated polyvinyl chloride (CPVC) thermoplastic. Spears® premium material, engineering, and production offer heavy duty mechanical durability, stress resilience, and chemical resistance for superior performance, reliability, and results. The fittings are manufactured in an ISO 9001 certified facility. They are tested and certified to comply with ASTM, NSF, and UL standards and can be used to meet EPA secondary containment requirements. DC termination fittings are rated for SCH 40 or SCH 80 operating pressures and working temperatures up to 140°F (PVC) or 200°F (CPVC).

Double containment termination fittings are precision engineered to deliver superior performance and reliability to ensure the highest operational safety and efficiency in secondary containment systems. The fittings are heavy duty, crafted from corrosion resistant materials to withstand harsh fluids and environments. Their compact, streamlined design facilitates easy assembly, reducing installation time and costs. Double containment termination fittings meet or exceed industry standards. This allows facilities to achieve regulatory compliance and mitigate concerns with leaks and environmental release, assuring owners of safe, legal operations.

• Enhanced Safety: Dual containment design provides a secondary barrier against leaks to protect both personnel and the environment.
• Chemical Resistance: PVC and CPVC materials for compatibility with a wide range of corrosive chemicals.
• Durability: Engineered for long term performance with high impact and stress resistance.
• Leak Detection: Compatible with various leak detection systems for proactive maintenance and preventative safety.
• Ease of Installation: Slip on sockets and prefabricated components reduce installation time and labor costs.
• Lightweight: Low weight synthetic makes for easy transport and installation.
• Compliance: Built to meet regulatory codes for containment and release prevention for applications handling hazardous materials.

Double containment termination fittings are essential to the completion of dual pipe systems by providing a starting and stopping point. The fittings material and engineering make them versatile and suitable for a wide range of work settings handling various liquid materials. Their primary function is to prevent leaks of hazardous or corrosive fluids, making them essential in environments where safety and regulatory compliance are paramount. DC termination fittings can be used in any plumbing system that requires or benefits from secondary containment and transporting fluids compatible with the fitting construction material. Common applications and uses include food and beverage production, chemical processing, municipal water treatment, wastewater collection and treatment, mining and metals, offshore platforms, oil and gas, pulp and paper, environmental remediation, plating and surfacing, semiconductor production, pharmaceutical manufacturing, agriculture, and renewable energy.
