About This Part
This end cap does the job of three parts in one: it locates a bearing, seals a micro fluid channel, and presents a quick-connect port, all from a single piece of SUS316. Because the fluid orifice, bearing seat, and flange pilot are machined in one clamping on a turn-mill center, their axes stay true to each other, which is what keeps the assembly leak free and free of side load on the bearing.
The bearing seat is held at Ø12 H7 with positional accuracy within 0.01 mm, and the critical fitting faces within 0.005 mm. The center orifice runs Ø2.1 ±0.05 mm with the flow path wall finished to Ra 0.8 um or better. A shallow 0.01 mm laser mark carries traceability without disturbing the sealing surfaces.
Every cap is CMM checked for position, coaxiality, and geometric tolerances, the H7 seat is verified with an air gauge or plug gauge, and a microscope pass confirms the micro burr condition and mark legibility. Parts leave cleaned, deburred, and ready for passivation.

Common Questions
Why SUS316 instead of 304 for a fluid end cap?
The added molybdenum in 316 resists pitting and chloride attack, which matters wherever process fluids or cleaning agents flow. It also carries better cleanliness credentials for fluid and analytical service.
Can the orifice and seat tolerances be adjusted to my drawing?
Yes, the dimensions shown come from a delivered lot. Send your drawing and we quote to your tolerances, flagging any feature that needs grinding or extra setup before you commit.
How is the part protected in transit?
Each cap is cleaned, deburr checked, and packed in individual bubble wrap inside an export carton, with the CMM and gauge records in the box.
