REIKU
Frequently asked questions
Common questions about REIKU from 3G Electric.
What materials are REIKU continuous-flex corrugated tubing connectors made from?
REIKU connectors for continuous-flex corrugated tubing are constructed from polyamide 6 (PA6), a thermoplastic known for its mechanical strength and resistance to abrasion and many chemicals. The fittings are black as standard. PA6 offers a balance of toughness and flexibility, making it suitable for dynamic applications where the connector must withstand repeated flexing without cracking. The material also provides electrical insulation and can operate in temperatures up to approximately 120°C, depending on the specific grade and conditions. For applications requiring higher chemical resistance or temperature ratings, alternative materials may be available, but the standard REIKU line uses PA6 for its combination of performance and cost-effectiveness.
What sizes of REIKU straight connectors are available?
REIKU straight connectors are available in a range of nominal sizes to accommodate different corrugated tubing diameters. Threaded straight connectors, such as the VPGRB series, come in sizes from 5/16 in to 1-1/2 in, with NPT thread connections from 1/4 in to 1-1/2 in. Flange connectors, like the PAGOB series, are offered for larger tubing sizes, including 2-1/4 in and 2-3/4 in. The nominal size refers to the tubing size the connector is designed to fit, while the thread size indicates the connection to the enclosure or panel. It is important to match both the tubing size and thread type to ensure a proper fit and seal. 3G Electric stocks a variety of these sizes to support different installation requirements.
How do I select the correct REIKU connector for my application?
Selecting the correct REIKU connector involves determining the tubing size, connection type, and environmental factors. First, identify the nominal size of the continuous-flex corrugated tubing you are using. Next, choose the connection type: threaded connectors (e.g., VPGRB series) are used for terminating at threaded ports, while flange connectors (e.g., PAGOB series) are used for mounting to flat surfaces or bulkheads. Consider the thread size (NPT) or flange dimensions to match your equipment. Also, verify material compatibility with any chemicals present and the operating temperature range. For dynamic applications, ensure the connector is rated for continuous flexing. 3G Electric provides detailed specifications for each SKU to assist with selection, and technical support is available for complex requirements.
What is the difference between REIKU VPGRB and PAGOB series connectors?
The REIKU VPGRB series consists of threaded straight connectors designed for continuous-flex corrugated tubing. They feature an NPT thread for connection to junction boxes, panels, or machinery. The PAGOB series comprises straight flange connectors, which are used to terminate or join corrugated tubing at enclosures or bulkheads using a flange mount. Both series are made from black polyamide 6 and provide secure connections for cable management systems. The choice between them depends on the mounting interface: VPGRB for threaded ports, PAGOB for flange mounting. VPGRB connectors are available in sizes from 5/16 in to 1-1/2 in, while PAGOB connectors are offered in larger sizes, such as 2-1/4 in and 2-3/4 in. Both series are suitable for dynamic applications where strain relief and protection are required.
Are REIKU connectors suitable for continuous flexing applications?
Yes, REIKU connectors are specifically designed for use with continuous-flex corrugated tubing, which is intended for applications where the cable management system must accommodate repeated motion. The connectors provide a secure termination that maintains strain relief and protects cables from mechanical stress. The polyamide 6 material offers good fatigue resistance, allowing the connectors to withstand the flexing cycles typical in robotics, automated machinery, and material handling equipment. However, the actual flex life depends on factors such as bend radius, cycle frequency, and environmental conditions. It is recommended to follow the tubing manufacturer's guidelines for minimum bend radius and installation to ensure optimal performance. REIKU connectors are tested to meet relevant standards for dynamic applications, but specific cycle life data should be obtained from the manufacturer for critical applications.
What thread types are available on REIKU straight connectors?
REIKU straight connectors are available with NPT (National Pipe Thread) connections in various sizes. The current 3G Electric inventory includes NPT threads ranging from 1/4 in to 1-1/2 in. For example, the VPGRB-10G00 has a 1/4 in NPT thread, while the VPGRB-48N08 features a 1-1/2 in NPT thread. These threads are commonly used in North American and international industrial applications. It is important to match the thread type and size to the mating port to ensure a proper seal. For applications requiring metric threads or other thread standards, alternative part numbers may be available. 3G Electric's product listings specify the connection type and size for each SKU, allowing customers to select the appropriate connector for their equipment.
