Manufactured from 304 or 316 stainless steel, these caps feature an AWWA C606-compliant grooved design that connects seamlessly with mechanical couplings, ensuring leak-proof performance in high-vibration and corrosive environments.
Durable Material Construction:
Available in 304 (general corrosion resistance) and 316 (chloride-resistant) stainless steel, with a minimum yield strength of 205 MPa and elongation ≥40% for impact resistance.
Smooth internal surface (Ra ≤1.6μm) prevents sediment buildup, while the grooved outer edge (depth: 2.4mm ±0.1mm) ensures a tight fit with couplings like Victaulic®.
Leak-Proof Sealing Design:
Integral EPDM or NBR gasket (depending on media) provides bubble-tight sealing up to 16 bar (232 PSI) for water/gas systems, with optional Viton® gaskets for chemical compatibility.
Reinforced dome shape distributes pressure evenly, reducing stress concentration at the pipe end during surges.
Easy Installation:
Requires no welding or threading—simply slide over the grooved pipe end and secure with a coupling, reducing installation time by 60% compared to welded caps.
Lightweight design (20% lighter than equivalent threaded caps) ideal for overhead and hard-to-reach installations.
Compliance & Testing:
Meet ASME B16.24, MSS SP-83, and AWWA C606 standards, hydrostatically tested to 1.5x working pressure for 30 minutes without leakage.
Passivated surface (for 316 caps) enhances corrosion resistance in marine and industrial environments.
Ideal for sealing and protecting pipe systems:
Water Distribution: Temporary closure of fire hydrant lines, water main extensions, and irrigation system endpoints, compliant with NSF/ANSI 61 for potable water.
Industrial Maintenance: Sealing unused branch pipes in chemical plants, refineries, and power stations, with 316 caps resisting aggressive media like seawater and sulfides.
Construction & Infrastructure: Protecting pipe ends during pipeline testing and commissioning, reducing contamination risks in municipal and industrial projects.
Marine Engineering: Sealing offshore platform pipelines and shipboard piping, with 316 stainless steel enduring saltwater exposure for 15+ years.
Q: Can these caps be used for permanent pipe termination?
A: Yes, they are suitable for both temporary and permanent sealing when paired with a mechanical coupling and appropriate gasket.
Q: What is the temperature range for EPDM gaskets?
A: -40°C to 150°C, while Viton® gaskets extend this to -20°C to 200°C for high-temperature applications.
Q: Do the caps require special tools for installation?
A: No, only a torque wrench to tighten the coupling bolts to the manufacturer's recommended value (typically 50-70 N·m for 2"-12" caps).
Q: Are non-magnetic options available?
A: Yes, 316L stainless steel caps offer low magnetic permeability, ideal for MRI facilities and sensitive electronic environments.
