Custom PTFE Hammer Union Seal Rings for Specified Chemical Service
Royal Way®Custom PTFE hammer union seal enquiries are specified by the finished ring drawing and intended chemical exposure. Provide the union manufacturer, figure and required profile together with the PTFE grade. Review each chemical, concentration and service condition for the selected construction.

Custom PTFE Ring Drawing and Chemical Exposure Requirements
For a custom ring, provide inside and outside dimensions, section profile, tolerances and the union assembly drawing. Specify the PTFE grade and any filler requirements. Confirm whether the requested item is the sealing ring or a supporting component within a defined assembly.
List the process chemicals, concentrations, mixtures and cleaning products together with temperature exposure and pressure cycles. Define the required compatibility review and acceptance documents for the selected material grade. A general chemical-resistance description does not establish suitability for every medium.
Agree the sample and finished-part inspection requirements before production. Use the hardness test method specified for the PTFE grade where applicable. The broader size and elastomer references retained below describe separate options and require their own drawing approval.

Material Introduction
| Material name |
Temperature range |
Advantage |
Deficiency |
| NBR(Buna) |
NBR service temperature by approved compound
Confirm operating exposure |
1.Presently the most widely used rubber in the seal industry
2.Exceptional balance of good mechanical properties, wear properties, and chemical resistance
3.Resistance to most mineral oils and greases |
don't used with gly-based brake fluids and strong acids |
| HNBR(Hydrogenated Nitrile) |
HNBR service temperature by approved compound
Confirm operating exposure |
1.Chemical resistance
2.Wider temperature range than standard nitrile
3.High strength material that resists extrusion, abrasion, and wear
4.Water and steam exposure requires compound-specific review
5.H2S exposure requires specific compound qualification
6.Commonly used with petroleum oils and co2 |
don't use with chlorinated hydrocarbons, polar solvents, or strong acids |
| FKM(Fluorocarbon) |
FKM service temperature by approved compound
Confirm operating exposure |
1.Excellent resistance to higher temperature, petroleum, and gasoline
2.Good chemical resistance, including to refrigerants(R12)
3.Great mechanical properties are retained over a wide temperature range
4.Ammonia exposure requires specific compound compatibility review
|
Check compatibility against the specific FKM formulation and complete fluid composition |
| PTFE (Polytetrafluoroethylene) |
PTFE service temperature by grade and assembly
Confirm operating exposure |
Confirm compatibility for the selected PTFE grade and process fluid |
Generally more expensive than other plastics or elastomers, which can be a limitation for cost-sensitive applications. |
PU (Polyurethane)
|
PU service temperature by approved grade
Confirm operating exposure |
1.Thermoplastic elastomer with higher tensile strength, toughness, and wear resistance
2.Great combination of hardness and elasticity
3.Excellent low temperature flexibility
4.Commonly used in high pesure hydraulic systems where parts are subject to wear
|
Can degrade when exposed to UV light over prolonged periods unless specifically formulated with additives for protection. |
