What to Know Before You Order
YSC-P-10A ESD Workbench Pipe Fitting 3/4" belongs to the family of cast and pressed fittings that hold a 28 mm tube frame together. Individually it is a small casting with one bolt; collectively these parts decide whether a workstation behaves as one rigid structure or as a set of tubes leaning against each other.
Points that decide whether it works
- Ask for the ESD version explicitly if the cell is grounded. A standard painted joint sitting in an otherwise dissipative workstation interrupts the path at the most inconvenient place.
- Specified torque for an M6 bolt in this family is typically 8 to 10 Nm. Two fitters working by feel will differ by up to a factor of two, and the frame that holds its rating is the one assembled with a wrench rather than a hex key and good intentions.
- Confirm the pipe you are joining: 28 mm OD is the standard, but wall thickness changes how much clamping travel the joint has. Thin-wall and thick-wall tube are not always interchangeable in the same fitting.
- Mark each joint with a paint pen once torqued. A broken line means something moved, and it is visible from across the aisle without touching the frame.
- Surface finish is a corrosion decision. Zinc plating covers general workshop conditions; chromed or electrophoresed finishes are for visible frames and light washdown; stainless is for humidity, washdown and coastal freight.
Frequently Asked Questions
How much load can this joint carry?
The joint is rarely the first thing to fail — the tube span usually gives way first, by sagging rather than breaking. What limits a frame is joint stiffness under sideways load, which is why torque and retorquing matter more than the catalogue weight figure.
What torque should I use?
Typically 8 to 10 Nm for an M6 bolt in this family, then again after 24 to 48 hours once the coating has settled. Use a wrench, not feel; the difference between two fitters is larger than most people believe.
Can it be reused after dismantling?
Mechanically yes, but clamping force depends on the coating recovering its thickness. After two or three assemblies the joint needs more torque to hold the same load, so treat reuse as a maintenance decision rather than a free option.
