Claims20
A fitting for vacuum assisted resin transfer molding comprising:
- a base including a central aperture passing through the base and surrounded by at least one aperture seal for engaging tubing inserted into the central aperture, a lower portion having two upward-facing base seals, and an upper portion including a threaded exterior and a threaded interior;
- a sealing washer, including two washer seals, adapted for abutting the lower portion of the base such that the inner edge of the two washer seals abut the outer edge of the two base seals;
- a sealing nut adapted to abut the sealing washer and to engage the threaded exterior of the upper portion to thereby cause the two washer seals to engage the two base seals to thereby form a seal about a vacuum bag;
- and
- an inner nut, including a nut aperture adapted to allow tubing to pass through, adapted to engage the threaded interior of the upper portion and to thereby cause the at least one aperture seal to compress and to form a seal about tubing as the inner nut is tightened.

A fitting for vacuum assisted resin transfer molding comprising:
- a base including a central aperture passing through the base and surrounded by three aperture seals, a lower portion having an inner and an outer upward-facing base seal, and an upper portion including a threaded exterior and a threaded interior;
- a sealing washer including an inner and an outer downward-facing washer seal, the sealing washer adapted for abutting the lower portion of the base such that the inner edges of the inner and outer washer seals abut the outer edges of the inner and outer base seals;
- a sealing nut adapted to abut the sealing washer and to engage the threaded exterior of the upper portion to thereby cause the inner and outer washer seals to engage the inner and outer base seals and to thereby form a seal about a vacuum bag;
- and
- an inner nut, including a nut aperture adapted to allow tubing to pass through, adapted to engage the threaded interior of the upper portion and to thereby cause the aperture seals to compress and to form a seal about tubing as the inner nut is tightened.
