FLEXAquick® RQB90-N NPT Plastic Thread Smooth Bend 90° Elbow
NPT-threaded 90° smooth bend elbow fittings with IP68 / IP69K sealing
RQB90-N 90° elbow plastic fittings with NPT threads are part of the FLEXAquick® quick-connect system, enabling fast, secure, and tool-free assembly of flexible conduit connections. The 90° smooth bend design provides a more gradual direction change than a hard 90° elbow, supporting compact conduit routing and a neat, low-profile installation within limited spaces.
Designed for use with ROHRflex® corrugated plastic conduits, RQB90-N fittings support machine building, automation, OEM wire and cable harnessing, transportation equipment, and industrial control installations where NPT thread compatibility and high ingress protection are required.
FLEXAquick® quick-connect fittings and ROHRflex® flexible corrugated conduits are flagship product lines from IBIS Electro-Products Corp, specializing in high-performance electrical conduit systems.
Select the correct fitting by matching the required NPT thread size, conduit outside diameter, bend-style routing requirement, and sealing requirement for the installation.

How to Choose the Right RQB90-N Fitting
Choose the correct RQB90-N fitting by matching the NPT thread size, conduit OD, bend-style routing requirement, and sealing level.
- Match the required NPT thread size
- Match the conduit OD
- Confirm the required bend-style elbow configuration
- Confirm the required sealing level
- Confirm ROHRflex® conduit suitability
- Use this fitting family where a smoother 90° conduit bend is preferred over a harder right-angle turn
Frequently Asked Questions about RQB90-N Fittings
What is the RQB90-N family used for?
RQB90-N fittings are used to terminate ROHRflex® corrugated plastic conduit into NPT-threaded panels, enclosures, and devices while providing a smooth bend 90° conduit entry and high ingress protection.
Why choose an RQB90-N fitting instead of a hard 90° elbow fitting?
RQB90-N fittings are chosen where a smoother bend is preferred instead of a hard 90° conduit turn. The smooth bend design can provide a cleaner, lower-profile conduit entry and is often preferred where a more gradual direction change is desired.
Do RQB90-N fittings require tools for conduit connection?
No tools are required for quick conduit connection or disconnection. The FLEXAquick® conduit side uses a quick-connect locking design for fast conduit attachment and release without compression nuts or ferrules. Standard installation procedures still apply for the threaded mounting side.
What sealing level do RQB90-N fittings provide?
RQB90-N fittings provide IP68 / IP69K sealing when installed correctly according to product specifications.
Which conduits are RQB90-N fittings designed for?
RQB90-N fittings are designed for use with ROHRflex® corrugated plastic conduits matched to the correct conduit OD.
Are RQB90-N fittings suitable for industrial applications?
Yes. RQB90-N fittings are suitable for machine building, automation, transportation equipment, OEM assemblies, and industrial control installations requiring compact NPT-threaded conduit entry and high ingress protection.
How do RQB90-N fittings differ from RQW-N fittings?
RQB90-N fittings use a smooth bend 90° elbow body, while RQW-N fittings use a hard 90° elbow body. RQB90-N is preferred where a smoother, lower-profile conduit entry is desired, while RQW-N is used for a sharper right-angle turn.
