Female Luer Caps

Female luer closures and seals molded for ports that have to open and close repeatedly without losing their seal.

Product Overview

What This Component Is

Female luer closures and seals molded for ports that have to open and close repeatedly without losing their seal. The cavity detail is small enough that tooling accuracy, not molding speed, decides whether the part works.

Key Benefits

  • Sealing face finish controlled in the tool so it does not depend on polishing luck
  • Repeat open and close performance reviewed during sampling
  • Clean room molded for parts that sit on an open fluid path
Female Luer 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 device makers
  • Diagnostic instrument OEMs
  • Assemblers of reusable access sets

Problems It Solves

  • Seals that hold on the first close and leak on the fifth
  • Cap geometry that fights the operator wearing gloves
  • Parts arriving with mould release residue on the sealing face

Application Scenarios

  • Repeat access ports on infusion lines
  • Sample port closures
  • Instrument maintenance ports
Technical Features

How It Is Engineered

  • Sealing face machined to a controlled finish rather than hand polished
  • Draft and undercut reviewed so the part releases without deforming the seal
  • Release agent use restricted 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

Elastomer plug closuresA molded closure gives a repeatable mechanical seal with no coring or fragment risk, which suits ports that are opened by gloved hands many times.
Outsourced sealing componentsHolding the closure and the fitting on tools in the same plant means the pair is validated together rather than hoped to fit.
Use Guide

How To Handle It

  • Test repeat open and close cycles during qualification, not only a single seal
  • Handle by the body rather than the sealing face
  • Replace the closure if the sealing face is visibly scored
Questions Buyers Ask

Questions About Female Luer Caps

Can you validate a closure against our port?

Send the mating part. We sample both together rather than testing the closure on its own, which is the only way the result means anything.

Do you use mould release on these parts?

Release agent is restricted on sealing surfaces. Where a part will not release cleanly we change the tool rather than spray the problem away.

What lead time should we plan for tooling?

It depends on cavitation and steel availability. Our mold division builds 350 to 400 sets a year, and we confirm a date against the schedule when we quote rather than before.
