Carbide Viton Metal Bellows Seal For Compressor Fix
✔️ Type 680 rotary shaft seal silicon carbide face viton bellows kit

This carbide and viton mechanical seal serves as a direct rotary shaft assembly rebuild kit for industrial air compressors and heavy duty liquid pumps. Replacing factory rubber lips with a matched silicon carbide stationary seat and temperature resistant metal bellows eliminates chronic fluid seepage and restores consistent pressure ratings across standard motor mounts.

✅ Factory type 680 configuration replaces worn o rings and packing glands in vertical or horizontal pump casings
✅ 1 ½ inch bore diameter aligns perfectly with common compressor crankshaft journals and coupling sleeves
✅ Silicon carbide CAR sliding interface works alongside VIT fluoroelastomer lips to handle oily and water based lubricants
✅ Reinforced metal bellows design absorbs axial movement while keeping internal leakage paths locked shut

💡 What makes a balanced rotary shaft seal handy for stopping compressor pump fluid loss? The fix relies on pairing a hard stationary face with a flexible dynamic element that tracks shaft movement without creating friction heat.

- Hard carbide sliding plates resist wear patterns that cause early seal failure during dry starts - Flexible viton lips swell slightly when exposed to petroleum oils to tighten the contact ring against the rotating sleeve - Corrugated stainless bellows flex outward when pressure spikes to redirect internal fluids back toward the reservoir✝️
