Vi er forpligtet til at yde hurtig og pålidelig service og sikre, at dine O-ringstætninger bliver leveret på kortest mulig tid uden at gå på kompromis med kvaliteten.
Vi arbejder effektivt for at levere højkvalitets O-ringstætninger til tiden. Her er en oversigt over hele produktionsprocessen:
Vi designer O-ringstætninger baseret på kundespecifikationer og fremstiller dem ved hjælp af materialer af høj kvalitet som NBR, FKM og EPDM for at sikre premium kvalitet.
Hvert parti af O-ringstætninger gennemgår streng kvalitetskontrol og test for at sikre trykmodstand og lækagesikker ydeevne, der opfylder industristandarder.
Når produktionen er færdig, pakkes O-ringstætningerne sikkert og sendes via pålidelige transportører for at sikre rettidig levering.
Til specialbestillinger tilpasser vi præcis størrelsen og materialet på O-ringene for at opfylde dine specifikke krav, hvilket sikrer en perfekt pasform.
An O-ring is a circular sealing element made of rubber or elastomer, used to block the passage of liquids or gases between two parts. It fits into a groove and is compressed during assembly to form a tight seal.
To measure an O-ring, use a caliper to determine the inner diameter (ID), outer diameter (OD), and cross-section (CS). The formula is:
OD = ID + 2 × CS.
Accurate measurements ensure proper sealing performance.
O-rings are widely used in hydraulic systems, automotive engines, industrial pumps, and pneumatic tools. They prevent leakage in both static and dynamic applications under pressure, heat, and chemical exposure.
You can buy high-quality O-rings directly from manufacturers like Hengoseal.com, which offers a wide range of sizes, materials (NBR, FKM, EPDM, etc.), and supports custom orders with no MOQ.
O-rings work by being compressed inside a groove between two surfaces. When pressure is applied, the O-ring deforms and creates a barrier that blocks the path of fluids or gases, forming a leak-proof seal.
To shrink an O-ring temporarily, place it in cold water or a freezer for a few minutes. This causes the rubber to contract slightly, which can help during assembly. However, it will return to its original size at room temperature.
