FAQ

Material, standards, surface treatment and installation points for this model; the data comes from the specification table on this page and from the national standards cited in the answers.

Q1What material is the sealing plug made of? What strength level does it reach?

The specification table on this page states: material is carbon steel / stainless steel (optional). Material certificates and mechanical property test reports can be provided with the goods; batch acceptance follows the specifications above.

Q2To which standard are sealing plugs produced and accepted?

Standards stated in the specification table on this page: per customer drawing / corporate standard; thread GB/T 196, GB/T 197 (ISO 965-1) 6g; ingress protection IP68 (IEC 60529). Dimensional inspection reports can be provided with the goods; batch acceptance is carried out in accordance with the above standards and the drawings agreed by both parties.

Q3What surface treatments are available for the sealing plug? How to choose?

Surface treatment specified in the specification table on this page: zinc-plated / passivated (optional). Different coatings differ in appearance, corrosion resistance and cost; select according to the service environment and the order agreement.

Q4Where are sealing plugs used?

Typical applications listed in the product description on this page: battery packs and electronics control enclosures; hydraulic and pneumatic manifold blocks; pumps, valves and fittings; outdoor equipment housings. Overview: the sealing plug uses a threaded connection combined with a sealing structure to close process holes, with an ingress protection rating of up to IP68. The threaded structure allows easy disassembly and inspection, making it suitable for process holes and inspection holes that require periodic checks or may need to be reopened, balancing sealing reliability with ease of maintenance.

Q5How to choose the seal material for sealing plugs?

Select according to the sealing medium, temperature and compression set requirements: nitrile rubber (NBR) is common for mineral oils, fluororubber (FKM) withstands high temperatures and chemical media, and silicone rubber offers good elasticity at low temperatures. O-ring sizes are selected per the GB/T 3452.1 series; avoid scratching and excessive stretching during assembly. (Applies to this model “Sealing plug”.)
