STP35–STP60 Bag-Opening Vacuum Cup Assemblies and Components
STP35 / STP60: What to Order
Choose the complete STP model, not just the cup size. This product lists threaded cup configurations, cup-only replacements, BM30-B configurations and a separate silencer option. They are different order items.
| Listed model group | Purchasing check |
|---|---|
| STP35-G2M / STP35-G2F | Choose the male or female threaded configuration and listed silicone colour. Match the thread and installed dimensions to the selected drawing. |
| STP60-G3M / STP60-G3F | Choose the STP60 configuration by its own drawing. Do not assume it fits the same mounting space or connection as STP35. |
| STP35 / STP60 Cup Only | A cup-only replacement option, not the same order item as a generator assembly. Confirm the existing holder interface. |
| STP35-BM30-B / STP60-BM30-B; BM20-B-M18 | Match the complete assembly label and included components. BM20-B-M18 is listed separately from the BM30-B configurations. |
| BM30-B — Built-In Silencer | A separately listed component; do not order it as a substitute for a complete cup assembly. |
Small orders and replacement checks
Use the model selector and quantity field for the exact item you need. If the old model is unknown, send a photo of the cup face and side, its measured dimensions, the mounting connection and the required quantity before ordering. Test an appropriate sample with the actual bag and machine cycle before scaling up.
What should a batch enquiry include?
List each complete model or SKU and its quantity separately. Include the delivery country, postal code, required arrival date and any supplier-registration or documentation requirements. Batch pricing, availability and requested documents need confirmation for the specific order; this page does not promise a fixed bulk discount or reserved stock.
Dispatch time is not arrival time
Check the current shipping and return policy and the available services at checkout. Processing time and transport time are separate. For a business quote, identify the final receiving address before confirming freight or tax coverage; a US forwarding address and a Mexico delivery address are different destinations.

STP35/STP60 Application and Product Details
Compare the handling task before changing cup families
For an STP replacement, keep using the complete model and assembly checks above. If the task is general part transfer rather than bag opening, compare the cup profile and hose-routing arrangement before choosing a different family.
The following pages are selection alternatives, not confirmed drop-in replacements for STP components or assemblies.
