5.5 mm Dispensing Valve Needle Seals
IKSONIC supplies replacement needle seals for 5.5 mm dispensing and paint-valve applications. This range includes three listed models in UPE and PEEK, including a stepped UPE option. The original application reference is Diansheng dispensing equipment. Confirm the exact valve model, seal profile and installation requirements before selecting a replacement; the equipment brand reference does not imply OEM authorization or affiliation.
Available Material and Model Options
| Model identifier | Listed material | Selection detail |
|---|---|---|
| UPE5.5*9*3/2 (stepped) | UPE | Stepped version |
| UPE5.5*9*4.2 | UPE | Separate UPE model |
| PEEK5.5*9*4.2 | PEEK | Separate PEEK model |
The model strings above retain the listed numerical sequences. The product title states a 5.5 mm application, but the units and dimension order within the complete model codes are not explicitly specified. Do not treat these codes as a verified inside-diameter, outside-diameter and height specification. Confirm the required dimensions and tolerances against the valve or an approved drawing.
Select by Model, Material and Operating Conditions
Choose UPE or PEEK according to the exact replacement requirement, rather than assuming that matching numerical codes make the materials interchangeable. The stepped UPE version also needs a separate profile check. Product photographs show multiple seals and appearances; colour alone should not be used to identify material or establish fit.
When comparing an existing seal, include a clear photograph of both faces and the stepped section where applicable. A photograph helps identify the profile but does not replace dimensional checks or establish the polymer grade.
For application review, provide the dispensed fluid, cleaning media, operating temperature, pressure and needle movement conditions. Oil exposure, wear, heat and chemical compatibility should be assessed for the selected material and actual service environment. No universal temperature limit, pressure rating or chemical-resistance guarantee is stated for this range.
China Factory and Wholesale Enquiries
Discuss your requirements with IKSONIC, a China manufacturer and supplier of replacement seals serving equipment manufacturers, maintenance buyers and wholesale distributors. For factory purchasing enquiries, include the selected model, quantity and any inspection or documentation requirements. Ask for model-specific pricing, availability and lead time instead of assuming that every listed option is ready to ship.
Frequently Asked Questions
Will these seals fit every Diansheng dispensing valve?
No universal fit is claimed. The application reference alone is insufficient; check your valve model, seal profile and dimensions before ordering.
Can the stepped UPE version replace either 4.2 model?
Do not assume interchangeability. The stepped option has a different listed model designation, and the UPE and PEEK choices must remain distinct.
What should I send for a quotation?
Send the selected model, quantity, valve identification and available seal dimensions or drawing, together with operating conditions. Contact IKSONIC to discuss your replacement-seal requirements.
