[18170] 70S - Modular External Coupling
| Pipe Size: 1-1/2" IPS |
Product Description
The Hollaender Speed-Rail® 70S – Modular External Coupling is a slip-on connector designed to join two sections of pipe externally, creating a strong mechanical splice without welding or threading. Unlike an internal coupling, the 70S fits around the outside of the pipe, making it ideal for applications where additional reinforcement, modular adjustability, or ease of installation is required. Its modular design allows it to be incorporated into a wide range of structural, railing, and support configurations, including existing systems.
Fabricated from high-strength aluminum-magnesium alloy, the 70S provides excellent corrosion resistance for both indoor and outdoor environments. The coupling installs quickly using zinc-plated set screws to lock the connector securely in place. Always verify the correct IPS pipe size before ordering to ensure a proper fit.
- Thermal Conductivity - (@77F, SI units): 0.24 cal/cm*s*K
- Heat Treatment - Achieves its physical and mechanical properties as-cast (F). This eliminates the time and cost of heat treating.
- Machinability - Excellent machinability as-cast, excellent surface finish and high dimensional stability.
- Corrosion Resistance - Highest of any cast alloy. It can be anodized for additional corrosion protection to a 0.7 mil thickness (215R1).
- Weldability - It can be welded by any of the inert gas processes, T.I.G. or M.I.G., using filler rod of 5356 or 5183.
Key Features
- Creates a secure external splice between two pipe sections
- Slip-on design—fast installation with no welding or threading
- Modular configuration supports a variety of structural layouts
- Made from corrosion-resistant aluminum-magnesium alloy
- Secured with zinc-plated set screws for dependable engagement
- Compatible with Hollaender Speed-Rail® modular pipe systems
Common Applications
- Joining two pipe sections in modular railing systems
- Repairing or reinforcing pipe assemblies
- Architectural and industrial pipe frameworks
- Pipe-based supports, barriers, and structural extensions
- Applications where an external splice is preferred over internal coupling
