SAM Chest Seal - COMBO
One vented seal and one occlusive seal in a single 6 oz package — the pairing that covers an entry wound that needs venting and an exit wound that needs closing. The vented half uses SAM's TRUFLOW™ rigid raised-dome valve, built to keep an airflow path open when the seal is compressed under armour or body weight.
1 valved + 1 non-valvedTRUFLOW™ raised-dome valveSKU CS203-EN · 6 ozNSN 6510-01-656-8718

A vent that closes when something presses on it is not a vent. The dome is the whole design argument, and it is worth understanding before you buy on price.

What's Included

One combo package holding two different seals. Tap to open.

VIEW ▾What's in the Package — single configuration · SKU CS203-EN
  • 1× SAM® Valved Chest Seal — vented, with the TRUFLOW™ rigid raised-dome one-way valve and large side vents. SAM Medical specifies the dome maintains a one-way airflow path from the chest cavity regardless of pressure applied to the seal, including under body armour.
  • 1× SAM® Non-Valved Chest Seal — fully occlusive, no valve
  • Both seals carry SAM's proprietary adhesive, specified by the manufacturer to seal and reseal through heat, cold, blood, sweat and the elements
  • Application tabs on each seal — one or both can be used for placement, for lifting the seal to burp a wound, and for removal
  • Two seals, one package. No gauze, no gloves, no shears, no instruction card and no decompression needle are included.
  • This is the combo pack. If you want two of the same type, the Valved 2.0 (CS202-EN) and the Non-Valved (CS201-EN) are sold individually.

Guideline status SAM Medical states this seal meets the CoTCCC-preferred features for chest seals. That is the manufacturer's own characterisation of the product against the guideline criteria; it is not the same thing as the CoTCCC naming this product, and no such naming is claimed here.
Origin Made in USA

Part numbers, NSN, weight, valve design, adhesive description and origin are as published by SAM Medical. Read the guideline row precisely: "meets CoTCCC-preferred features" is SAM Medical's statement about how the design lines up with the criteria, and it is reproduced with that attribution intact rather than compressed into an endorsement. Application, as the manufacturer describes it: expose the wound and wipe the site clear of blood and moisture; select the valved seal for the entry wound and the non-valved seal for the exit wound or a second anterior wound; centre the seal and press firmly from the centre outward using one or both tabs; confirm the TRUFLOW dome is not obstructed by clothing, armour or bandaging; then monitor. The manufacturer's own instruction on deterioration is to use a pull tab to burp the seal, and if that does not resolve it, to proceed to needle decompression per TCCC Guidelines — an intervention that belongs to whoever is trained and authorised to perform it, which is a different question from who is carrying the seal. Seal dimensions are not published on this listing; if you are checking fit against a specific pouch, ask before you order.

Who Carries It

Military medics and corpsmen procuring against NSN 6510-01-656-8718, particularly where seals get compressed under plate carriers and transport straps · Tactical and law enforcement medics whose casualties are frequently armoured, moved and lain on · EMS and fire responders carrying a matched pair for a through-and-through rather than two of the same seal · Range and hunting parties where penetrating thoracic trauma is the realistic worst case · Kit builders who want the entry and exit answer in one package.

Applying a chest seal to an open chest wound is within the scope of TCCC and TECC-trained responders and, in most jurisdictions, of bleeding-control-trained bystanders. What follows the seal is not: recognising tension physiology, deciding to burp, and needle decompression are separate skills with separate authorisation, and the seal in the pouch does not confer any of them. Carry the pair, apply what you are trained to apply, and know in advance who on scene can do the next step.

CLINICAL RATIONALE

Evidence & Training Rationale

  • Guideline-aligned: CoTCCC recommends vented chest seals for all open/sucking chest wounds; use non-vented only if vented is unavailable.
  • Mechanism of benefit: Rapid occlusion prevents air entrainment; one-way vent helps egress air/blood to reduce risk of tension physiology.
  • Design notes: TRUFLOW™ raised-dome valve with large side vents aims to maintain outflow even under external pressure or body armor.
  • Training tip: After application, reassess breathing frequently. If deterioration occurs with a non-vented seal, momentarily lift an edge (“burp”) and consider needle decompression per protocol.
