Wear Resistance Rubber Bung With Hole , Silicone Rubber Stoppers One Hole

1: Express: S.F. ,DHL,UPS, TNT, FedEx ect, for urgent and small order.

2: Air shipment: air port to air port , or air port to door.

3: Sea shipment: suitable for bulk goods. it will takes more longer time than air shipment.

1. How do I choose the single-hole diameter?
Start with the measured tube or probe outside diameter and its tolerance. Specify whether the fit should grip the component or allow removal, and provide the insertion depth.
Confirm the fit on a sample assembly; rubber hardness, hole finish and component surface all influence insertion force.
2. What matters for repeated insertion?
a. State the expected insertion and removal cycle count.
b. Provide the component surface finish and any sharp edges.
c. Agree acceptable hole-edge damage and permanent deformation.
d. Specify permitted assembly aids and cleaning residues.
e. Define acceptable insertion and withdrawal forces.
f. Include leakage checks when the assembled stopper must seal.
g. Review the tested compound and geometry together before approval.
3. Is every silicone stopper suitable for heat or chemical exposure?
1. Temperature limits depend on the selected silicone compound.
2. Identify fluid composition and cleaning chemicals.
3. Provide exposure time and normal and peak temperatures.
4. Specify the desired hardness within the listed 40–80 Shore A options.
5. Food-contact or medical use requires applicable compound documentation and application validation.

4. What is needed for a replacement bung?
1. An original sample or dimensioned drawing.
2. The receiving opening and stopper insertion depth.
3. The tube or probe diameter and hole location.
4. Compound, hardness, color and quantity.
5. Agreed dimensional, retention and leakage acceptance criteria.

For a single-hole silicone bung enquiry, include the stopper profile and mating tube or probe dimensions, with the operating medium and installation requirements.

Custom parts can be reviewed from drawings or samples. Approve the bore fit and stopper-to-opening fit on a trial assembly before production.
