Pöppelmann KAPSTO is the world’s leading manufacturer of precision plastic protective caps and plugs, with over 4,000 standard dimensions — which is to say, if you have a thread, port or shaft to protect, the part already exists. Phil Industries is the authorised Singapore distributor, supplying customers across Singapore, Malaysia and Indonesia. (The brand is also commonly searched as Poppelmann KAPSTO.)
These protective elements seal and protect threads, ports, connectors, flanges, tubes and shafts during manufacturing, surface treatment, transport and final assembly. Therefore they earn their keep between processes, not in the finished product.
Caps or plugs — which do you need?
| Family | Protects | Types | Typical use |
|---|---|---|---|
| Caps (external) | Outside surfaces | Protective, Grip, Screw, Flange | Threaded studs, machined faces |
| Plugs (internal) | Inside bores | Protective, Grip, Screw, Flange | Ports, hydraulic and pneumatic fittings |
In short: a cap goes over, a plug goes in.

Frequently asked questions
What is Pöppelmann KAPSTO?
It is Pöppelmann’s range of standard plastic protective caps and plugs. Because the range runs to 4,000+ dimensions, most requirements are met from a standard part rather than a custom tool.
Are the caps and plugs reusable?
Many are. Grip and screw variants in PE and PP survive repeated fitting, so lines that cycle parts through surface treatment often reuse them. However, single-use grades are cheaper where the part ships out and does not return.
Can they be used for paint masking?
Yes — the range includes grades that withstand powder-coating and paint-masking temperatures. Therefore send us the process temperature along with the thread size.
Do you stock Pöppelmann KAPSTO in Singapore?
Yes. We hold bulk case quantities for fast delivery across Singapore. In addition, our team can match a KAPSTO part number to your thread or port dimension — WhatsApp +65 9853 9030 or call +65 6555 1745.
