Compatible Air End Repair Kit
The Dayton 6PY77 kit services air ends on models 6PY37 and 6PY38. It supplies the gaskets, O-rings and seal rings required for a complete rebuild. Maintenance teams use it to restore sealing performance on compatible units. The kit matches Grainger part numbers 6PY37, 6PY37A, 6PY38 and 6PY38A.
Thermals Noise and Power Draw
This repair kit contains only static sealing components and has no moving parts, electrical draw or fan assembly. It adds no heat, noise or power consumption to the host machine during normal operation. Installation simply replaces worn seals with new items from the kit. The air intake connection size and pressure ratings remain governed by the original unit.
Sustained Load Behavior
Under continuous duty the fresh gaskets and O-rings maintain a consistent seal without degradation. The kit includes all rings needed for the air end, so leakage does not increase over extended run periods. No diaphragm material is involved, eliminating a common wear point. Compatible connection media type stays air as specified by the original equipment.

Questions about this item
How do I install the Dayton 6PY77 repair kit on my 6PY37 air end, and which step is most often done incorrectly?
Remove the air end from the pump, disassemble the housing, then replace all gaskets, O-rings and seal rings from the kit. The step most often done incorrectly is skipping the cleaning of every sealing groove before fitting the new rings.
What maintenance will the Dayton 6PY77 kit require after it is fitted to a 6PY38 air end?
Inspect the new gaskets, O-rings and seal rings at each scheduled service interval. Replace any that show hardening, cracking or compression set to keep the air end sealing correctly.
What is the first limit that appears when the 6PY37 air end runs continuously after a 6PY77 kit install?
The first limit is heat buildup in the air end housing; sustained operation without adequate cooling will degrade the fresh seals and gaskets faster than normal cycling.
