Product Overview
Nylon Cable Gland Blanking Plug
Unused knock-outs and entry holes in enclosures are often overlooked — yet they remain the most direct path for dust and contaminants to reach sensitive components. The GNPR blanking plug is engineered for simple push-in installation with no tools required, letting you seal unused holes in seconds during panel assembly.
Made from black PA nylon, GNPR is suitable for general industrial environments. Use alongside Good Gi cable glands to deliver a complete hole management solution — active entries sealed with cable glands, unused entries sealed with GNPR.

FAQ
Q1｜Why do unused holes in an enclosure need to be sealed?
An enclosure's IP protection rating is tested with all openings sealed. Any unsecured hole — even a small one — effectively nullifies that rating, allowing dust, insects, and moisture to enter freely. Blanking plugs are the simplest and most cost-effective way to maintain the intended protection level.
Q2｜How is the GNPR installed? Are any tools required?
GNPR uses a push-in design — align the plug with the hole and press it in. No tools, no threading. This makes it especially efficient on panel assembly lines or wiring projects where dozens of holes need to be sealed quickly.
Q3｜What material is GNPR made from? How durable is it?
GNPR is manufactured from PA (polyamide) nylon, suitable for general industrial environments and capable of maintaining a long-term seal under normal operating conditions. The black color also matches most enclosure finishes and Good Gi cable gland accessories for a consistent appearance.
Q4｜How do I select the correct size?
Check the hole diameter on your enclosure and match it to the corresponding GNPR size from the specification table. A plug that is too small will not hold; one that is too large will not fit. Contact our sales team for sample confirmation if needed for large-quantity orders.
Q5｜What other blanking plug options does Good Gi offer? How do they compare?
Good Gi offers several hole-sealing solutions to suit different requirements:
・Nylon Screw-in End Cap (GSPN): Same PA nylon material as GNPR, but with a threaded design for a locked, more secure fit — ideal where the plug must not loosen over time.
・Sealing Plug Rod (GSP): Also push-in, but made from EPDM rubber for superior flexibility and sealing conformance.
・Hex Socket Blanking Plug (GQNEFSP): PA nylon, hex socket screw-in, IP68 rated — designed for wet or high-vibration environments requiring a fully certified seal. (Coming soon)
GNPR is the best choice for fast, tool-free installation in general-duty panel wiring applications.
