HUDY 203050 O-Ring Pump Seal Maintenance

The HUDY 203050 O-Ring is a handy spare to help keep HUDY Air Vac Vacuum Pumps running reliably. At 50x4 it fits models #104002 and #104004 for a precise seal and steady suction.

Role of the 203050 O-Ring

This O-ring creates the vacuum seal that prevents air entering the system and preserves pump draw. Keeping the seal in good condition is important when pulling tyres, gluing parts, or working on moulding tasks that need steady suction.

Quick Fit Tips for the Workshop

  • Clean the pump seat thoroughly to remove dust and adhesive residue before fitting the new ring.
  • Use a light smear of silicone grease to reduce friction and extend service life.
  • Seat the O-ring evenly and rotate it slightly to confirm correct alignment and no pinching.
Remark :
Due to limited stock availability, please notice that some HUDY items may have to order from the factory and the ready time is around 8-12 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I fit this O-ring to non HUDY pumps?

The HUDY 203050 O-Ring is made for HUDY Air Vac models #104002 and #104004. It may match other pumps with the same 50x4 seating dimensions, but fit is not guaranteed without checking measurements.

How do I know when the O-ring needs replacing?

Inspect the O-ring for cracks, flat spots, or hardening. If suction drops or you notice air leaks around the seal, replace the ring to restore proper vacuum.

What maintenance keeps the O-ring lasting longer?

Keep the seal clean, avoid solvents that degrade rubber, apply a light silicone lubricant, and store spare rings away from heat and direct sunlight to preserve elasticity.
