Luer Lock Caps

Small molded luer caps and closures that seal an open port between procedures.

Product Overview

What This Component Is

Small molded luer caps and closures that seal an open port between procedures. They are the kind of part that is trivial until a lot arrives with inconsistent thread engagement and the assembly line stops.

Key Benefits

  • Thread and taper detail cut in the tool rather than corrected at assembly
  • Micro parts handled by a tool room that works at 0.002 mm on mold steel
  • Automated molding cells for the repeat volumes caps are ordered in
Luer Lock Caps produced by Sanpin Medical
Molded on tooling we cut ourselves in Shenzhen. Certification covers the site doing the work: ISO 9001:2015 and ISO 13485:2016.

Who It Is For

  • Infusion set assemblers
  • Sampling device brands
  • Kit packers needing a matched closure

Problems It Solves

  • Caps that loosen in transit and arrive unsealed
  • Thread engagement varying between cavities
  • Minimum order quantities from suppliers who do not want small parts

Application Scenarios

  • Port closure on infusion and sampling lines
  • Transport protection for filled devices
  • Instrument service ports
Technical Features

How It Is Engineered

  • High cavitation layouts for parts of this size
  • Thread form spark eroded so the profile is repeatable
  • Automatic part handling to avoid finger contact on sealing surfaces

Materials

  • Medical grade resin selected against your specification rather than substituted by us
  • Customer nominated grades accepted where a device master record already fixes the material
  • Colourants and additives confirmed in writing before the first sampling run

Figures above are plant and tooling capabilities recorded on our own site. Part level tolerances are confirmed against your drawing at mold flow review rather than quoted as a blanket number.

Manufacturing Process

  1. Mold design review
  2. Steel machining and EDM
  3. Mold trial and cavity sampling
  4. Clean room or conventional molding
  5. In process dimensional check
  6. Clean room packing

Quality Control

  • Cavity by cavity dimensional sampling before a tool is released
  • In process checks during the molding run rather than only at the end
  • ERP system records the lot, tool and machine behind every shipment

Customization Options

  • Cavitation sized to your annual forecast instead of a fixed standard tool
  • Colour and resin grade to your specification
  • Clean room packing format and labelling agreed before the first shipment
Comparison

Compared With Other Routes

A generic stock capA stock cap is designed for someone else's port. A molded cap on your own tool is dimensioned for the fitting you actually ship.
Hand packed closuresAutomatic handling keeps fingers off the sealing face, which matters more on a cap than on almost any other small part.
Use Guide

How To Handle It

  • Confirm thread engagement torque during sampling
  • Keep caps in the supplied bag until the point of use
  • Do not re use a cap once it has been removed from a filled device
Questions Buyers Ask

Questions About Luer Lock Caps

Is there a minimum order quantity?

We build tooling for small parts routinely and size cavitation to your forecast, so the practical minimum is set by tool economics rather than a fixed order rule. Send your annual volume with the enquiry.

Can you match an existing cap we already buy?

Send a sample and the drawing. We measure it in our tool room and tell you honestly whether we can match it or whether the original tool has drifted.

Which resin do you use?

The resin is your specification. We do not substitute grades, and any colourant is confirmed in writing before the first sampling run.
