Built for Automated Medical Device Manufacturing, Not Just Testing

The FasTest LuerMate ML is a pneumatically actuated external connector that seals against any full thread standard luer. It is designed from the outset for automated and semi-automated production — available in pneumatic, semi-automated, and fully-automated actuation — which makes it a component to be built into equipment rather than a hand tool used alongside it.

What sets it apart from a conventional leak test connector is visible in what it is designed for. Alongside leak and burst testing, the list includes balloon pleating and folding, heart valve crimping, and stent crimping. Those are not tests — they are manufacturing processes, in which the device has to be held pressurised or inflated while it is physically worked on. A connector serving those processes has to maintain a stable, repeatable luer connection for the duration of an operation, not just long enough to take a reading.

That is also why the specially designed luer nest matters. Burst testing is destructive by design, and crimping and pleating put the device under mechanical load while it is pressurised. The nest contains the test part under pressure — keeping the device located and controlled through operations where something is deliberately being pushed to or past its limit.

For medical manufacturing, the material and preparation specifications matter as much as the mechanics. The FasTest LuerMate ML is cleaned and lubricated for oxygen safe environments and uses FDA approved seals. It is one of four connectors in the FasTest LuerMate family, alongside the MLL, the MLH, and the 60M.

The Problem the FasTest LuerMate ML Solves

Connecting to a luer on a medical device production line is harder than the size of the fitting suggests:

• Hand-tightened luers are not repeatable: A luer connection made by hand varies with operator technique and torque. In a validated production process, that variability shows up as inconsistent results — and it cannot be automated.
• The connection has to hold through the whole operation: Pleating a balloon or crimping a stent means the device stays pressurised while it is mechanically worked. The connection must remain stable throughout, not merely long enough for a measurement.
• Parts under pressure need containing: In burst testing the device is taken to failure on purpose. Without something holding it, a part that lets go is both a safety concern and a contamination and cleanup problem in a controlled environment.
• Medical manufacturing constrains materials: Seal materials and preparation are not free choices. Cleanliness for oxygen service and FDA approved seal materials are prerequisites, not upgrades.

The FasTest LuerMate ML addresses all four: pneumatic actuation makes every connection identical and automatable, the luer seal holds through extended processes, the luer nest contains the part under pressure, and the connector is prepared for oxygen safe environments with FDA approved seals.

Key Features 

Seals Against Any Full Thread Standard Luer

The FasTest LuerMate ML connects to full thread standard luers across the range, so a line handling devices from different programmes or suppliers is not matching a different connector to each luer. The seal is made externally against the luer, with no threading by hand and no variation in how tightly it is done.

Designed for Automated Processes and High-Volume Production

Available in pneumatic, semi-automated, and fully-automated actuation, the FasTest LuerMate ML is built to be designed into production equipment. Every connection is made with the same actuation force, which is what makes results comparable across a shift and across a validated process — and it removes the operator as a variable in high-volume work.

Cleaned and Lubricated for Oxygen Safe Environments, with FDA Approved Seals

The FasTest LuerMate ML is cleaned and lubricated for oxygen safe environments and fitted with FDA approved seals. In medical device manufacturing these are qualifying requirements rather than optional extras — a connector that does not meet them cannot be used regardless of how well it performs mechanically. Confirm the specific preparation and seal specifications for your application with FasTest.

Specially Designed Luer Nest Contains the Test Part Under Pressure

The luer nest holds and contains the test part while it is under pressure. That matters most in burst testing, where the device is deliberately taken to failure, and in crimping and pleating operations, where the part is under mechanical load while pressurised. Containing the part keeps it located through the operation and keeps a failure controlled rather than uncontained.

Technical Specifications

Where the FasTest LuerMate ML Is Used

Leak and Burst Testing

The FasTest LuerMate ML connects to the device’s luer for leak and burst testing in automated production. In burst testing the part is taken to failure by design, which is where the luer nest earns its place — containing the device through a deliberately destructive test.

Balloon Pleating and Folding

Balloon catheters are pleated and folded as part of manufacture, with the balloon held under controlled pressure while it is formed. The FasTest LuerMate ML maintains that connection through the operation, with pneumatic actuation giving the same connection every cycle across a production run.

Stent Crimping

Crimping a stent onto a balloon requires the balloon to be held at controlled pressure while the stent is compressed onto it. The LuerMate ML provides the stable, repeatable luer connection that process depends on — and being automatable, it fits directly into crimping equipment rather than sitting beside it.

Heart Valve Crimping

Transcatheter heart valves are crimped to delivery diameter under controlled conditions. As with stent crimping, the FasTest LuerMate ML supplies a consistent pressurised luer connection throughout the operation, on devices where the cost of a mishandled part is substantial.

Frequently Asked Questions

Q: What is the FasTest LuerMate ML?

A: The FasTest LuerMate ML is a pneumatically actuated external connector that seals against any full thread standard luer. It is designed for automated and semi-automated medical device production — leak and burst testing, balloon pleating and folding, and stent and heart valve crimping.

Q: What does the LuerMate ML connect to?

A: Medical luers — it seals externally against any full thread standard luer, with no hand threading required.

Q: What is the luer nest for?

A: It contains the test part while it is under pressure. That matters in burst testing, where the device is deliberately taken to failure, and in crimping and pleating, where the part is under mechanical load while pressurised — the nest keeps the device located and any failure contained.

Q: Can the LuerMate ML be used in automated equipment?

A: Yes — it is available in pneumatic, semi-automated, and fully-automated actuation and is intended to be designed into production equipment. Automated actuation is also what makes every connection identical, which removes the operator as a source of variation.

Q: Is the LuerMate ML suitable for oxygen environments?

A: It is cleaned and lubricated for oxygen safe environments. Confirm the specific preparation requirements for your application and facility with FasTest before specifying.

Q: Does the LuerMate ML use FDA approved seals?

A: Yes. FasTest specifies FDA approved seals for this connector. Contact FasTest to confirm the seal specification for your particular application.

Q: What manufacturing processes is the LuerMate ML used for?

A: Beyond leak and burst testing, it is used in balloon pleating and folding, stent crimping, and heart valve crimping — processes where the device must be held pressurised while it is physically worked on, rather than just measured.

Q: What is the difference between the LuerMate ML, MLL, MLH, and 60M?

A: All four are FasTest LuerMate connectors for medical luers. The ML connects to full thread luers and is built for automated and semi-automated processes. The MLL is a seal-only connector for luers in automated and semi-automated processes, rated to 100 psi (6.9 bar). The MLH connects to full thread luers at 500 psi (34.5 bar). The 60M connects to medical thread luers at 750 psi (51.7 bar). Contact FasTest to confirm which suits your device and process.

Q: What industries use the LuerMate ML?

A: Medical device and life science manufacturing — particularly catheter, stent, and heart valve production, where luer-connected devices are tested and processed in validated, high-volume environments.
