What is the difference between a monitoring and an angiographic manifold?

A hemodynamic monitoring manifold runs on an arterial pressure line at monitoring pressures, usually with a flush device. An angiographic manifold is built for high-pressure contrast power injection, rated up to roughly 1,200 psi. They are different parts for different procedures — don't substitute one for the other.

How many gangs do I need?

Match it to your customers' procedure mix: 2-gang for simple setups, 3-gang as the common workhorse, 5-gang for complex multi-line procedures. More gangs add cost and dead space, so don't over-spec.

What pressure rating is needed for contrast injection?

Power injection is commonly rated up to about 1,200 psi, matched to the injector's peak. We confirm the exact rating per configuration before you order.

How to choose a cath-lab manifold

A manifold is one of the most configuration-dependent parts you'll source. Get five decisions right and you order the correct part the first time. Here is the framework we walk distributors through — and the mistakes that cost a re-order.

Five decisions that define the part

Monitoring, or high-pressure?

This is the fork everything else hangs on.

A hemodynamic monitoring manifold sits on an arterial pressure line, usually with a flush device, and runs at monitoring pressures. A high-pressure angiographic manifold is built for contrast-media power injection — pressures that reach roughly 1,200 psi. Put a monitoring manifold on a power injector and it can leak or fail. If your customers do both, you will likely stock both.

How many gangs — 2, 3 or 5?

Gang = the number of stopcocks built into the manifold.

More gangs mean more simultaneous lines and access points. A 2-gang suits simple setups; the 3-gang is the common workhorse for most cath-lab and ICU procedures; the 5-gang is for complex multi-line work. Match the count to your customers' procedure mix, not to the highest number.

What pressure rating does the procedure need?

State the peak pressure the part will see.

Monitoring lines run low. Power injection runs high — commonly rated to the injector's peak, up to about 1,200 psi. We confirm the exact rating per configuration before you order, so the part is matched to the procedure rather than guessed.

Sterile or non-sterile?

Depends on who does the final sterilisation.

EO-sterile if it ships ready to use; non-sterile if your customer sterilises in-house or the manifold is a component inside a larger kit you assemble. We supply either, validated per batch, to your market's requirement.

Connector standard, flush and extension?

The finishing details that decide fit.

Confirm the Luer / ISO connector standard, whether a monitoring build needs an integrated flush device, and whether an extension line is fitted. An extension / flush line is not fitted as standard — it is added to order.

Monitoring vs high-pressure, side by side

The two manifold families answer to decision #1 — here is how they differ in practice.

Match your scenario to a configuration

What we'd typically recommend by the work your customers do.

ICU / arterial pressure monitoring

Monitoring manifold · 3-gang · with flush device

Angio suite, contrast power injection

High-pressure angiographic manifold · rated to the injector

Mixed cath lab (both procedures)

Stock both families · common gang counts (2 & 3)

Component inside your own procedure kit

Non-sterile build · your configuration · bulk packed

Four spec mistakes that trigger a re-order

A monitoring manifold on a power injector

The single most expensive mistake — the part is not rated for injection pressure and can leak or fail. Specify the high-pressure family for any contrast injection.

Choosing gang count by the biggest number

A 5-gang costs more and adds dead space you don't need. Match the count to the actual procedure mix.

Assuming flush / extension is included

It isn't fitted as standard. If your customer expects it, say so up front and we build it in.

Ordering without a stated pressure rating

Always pin the peak pressure. A part that 'looks the same' can be rated very differently.
