Boeing BMS 5-133 Flame-Retardant Carpet Tape — Type & Class Explained

What BMS 5-133 covers, how to read a Type II callout, and the Polyken 108FR that carries it — in stock, free US shipping — $31.99 per roll, from $20.83 per roll by the case.

Boeing Material Specification BMS 5-133 covers pressure-sensitive, flame-retardant carpet tapes used to secure carpet and floor coverings in aircraft cabins, where the tape has to pass FAR 25.853(a) flammability requirements. The specification sorts tapes by Type and Class. For the standard Type II, Class 1 & 2 callout, the tape we stock is the Polyken 108FR — a double-coated cloth tape with a flame-retardant rubber adhesive.

New to Boeing specs? BMS 5-133 is a material specification. Polyken 108FR is also listed in BAC5034-4, a Boeing process specification. See our BMS vs BAC guide → for what that difference means when you order.

A tape data sheet reports testing against the specification's criteria. Final compliance depends on the specific tape, substrate, installation and approved aircraft procedure. Match the Type and Class on your drawing before you order.

What the BMS 5-133 callout codes mean

BMS 5-133 sorts carpet tapes by Type, which tracks construction and weight, and Class, which tracks adhesive color. Below is what each designation covers and whether we stock it:

Type II, Class 1

Standard-weight double-coated carpet tape with natural adhesive — beige on the roll. The most common cabin-carpet callout. In stock as 108FR Beige.

Type II, Class 2

The same standard-weight construction with black adhesive, chosen where a dark adhesive line is preferred. In stock as 108FR Black.

Type III

The heavier-weight class, for higher-hold applications. Not a grade we stock — send us the callout and we will check availability with the manufacturer.

Type IV

The lightweight differential-tack class, used where weight saving matters. Not currently available from the manufacturer — see the section below.

Read the Type and Class off your drawing, not off this page. What each Type and Class requires is defined in the Boeing specification, which is the controlling document and which we do not republish. What we can tell you is which designations the 108FR is listed to — Type II, Class 1 and Class 2 — and that its data sheet names BMS 5-133 directly. If your drawing calls out anything else, send it to us and we will check it before you buy.

Type IV callouts — current status

We regularly get RFQs for BMS 5-133 Type IV, the lightweight differential-tack class formerly served by the Polyken 1111. That product is not currently available from the manufacturer.

If your drawing specifically requires Type IV, send us the callout — we can advise on status and alternatives. What we will not do is supply a Type II tape against a Type IV callout: they are different constructions, and a substitution needs approval under your own engineering procedure, not ours.

Typical values are stated at time of manufacture and are not for use in writing specifications. Note the operating range starts at 40°F, not −40°F — this is a rubber-adhesive carpet tape, not a low-temperature product. Always verify against the controlling drawing and the current manufacturer data sheet for your application.

What Polyken 108FR costs

Stocked in 2″ × 25 yd rolls in both adhesive colors, at the same price either way. Quantity breaks run to 35% off at a full case:

Pack (2″ × 25 yd) Total Per roll Saving
1 roll $31.99 $31.99 —
3 rolls $86.37 $28.79 10%
8 rolls $204.74 $25.59 20%
Case — 24 rolls $499.99 $20.83 35%

Beige and black are priced identically, so the Class 1 or Class 2 choice costs you nothing either way. Prices are the listed prices at the time of writing and can change — confirm on the product page, or ask us about a quantity that is not listed.

Cross-referencing the Nitto P-55

Polyken 108FR is the cross-reference we supply against the Nitto P-55, and it carries BMS 5-133 on its own data sheet. A cross-reference identifies a potentially matching product — it is not a substitution approval, and swapping one for the other still needs sign-off under the applicable aircraft, operator or engineering procedure. See the side-by-side and our substitution guidance on the Nitto P-55 alternative page.

Frequently asked questions

What is Boeing BMS 5-133?

BMS 5-133 is a Boeing Material Specification for flame-retardant pressure-sensitive carpet tapes used to secure carpet and floor coverings in aircraft cabins. Tapes are sorted by Type, which tracks construction and weight, and by Class, which tracks adhesive color, and they must pass FAR 25.853(a) flammability requirements.

What is the difference between BMS 5-133 Type II Class 1 and Class 2?

Both are standard-weight double-coated carpet tapes and the difference is adhesive color: Class 1 is natural, which looks beige on the roll, and Class 2 is black. The Polyken 108FR is supplied in both, at the same price, so the same product satisfies either callout depending on the color you select.

Which tape meets BMS 5-133 Type II?

The Polyken 108FR is the tape we stock for BMS 5-133 Type II, Class 1 and 2. It is a double-coated cloth tape with a flame-retardant rubber adhesive, and its data sheet also names Boeing BAC5034-4, FAR 25.853(a), Douglas DMS 1971, Lockheed LAC C-24-1257, Embraer MEP 06-048, Fokker FK05-121 and FK05-197, Airbus ABD0031 and Bombardier DSC 91-8-1 and 91-8-2.

Do you carry BMS 5-133 Type IV?

Type IV is the lightweight differential-tack class, formerly served by the Polyken 1111, and it is not currently available from the manufacturer. We can advise on status and alternatives, but a Type II tape cannot be substituted where Type IV is specified — that is a different construction and needs approval under your own engineering procedure. Send us your drawing callout.

Does Polyken 108FR meet FAA flammability requirements?

Per the manufacturer data sheet, the 108FR is tested to FAR 25.853(a) with a 4.5 inch burn length and a 1.5 second exiting time, and drip exiting is listed as N/A. Confirm against the current data sheet for your specific application and substrate.

How much does BMS 5-133 carpet tape cost?

A single 2 inch by 25 yard roll of Polyken 108FR is $31.99 in either color. Three rolls work out at $28.79 each, eight rolls at $25.59, and a full case of 24 at $20.83 a roll — 35 percent off the single-roll price. Prices can change, so confirm on the product page.

What widths and roll lengths does Polyken 108FR come in?

We stock it in one size: 48 mm by 23 m, which is 2 inches by 25 yards, in beige and black. It is available as single rolls, 3 and 8 packs, or cases of 24. If your drawing calls for a different width, send us the callout and we will check what the manufacturer can slit and what the lead time would be.

What temperature range does Polyken 108FR handle?

Its data sheet gives an operating range of 40°F to 200°F, which is 4°C to 93°C. Note that the lower limit is positive 40°F rather than minus 40°F — this is a rubber-adhesive carpet tape rather than a low-temperature product, so if your application sees sub-freezing service temperatures, tell us and we will confirm suitability with the manufacturer.

Do you supply a Certificate of Conformance with BMS 5-133 tape?

A Certificate of Conformance is included with every order where available. It is what ties the roll you received to the specification your drawing calls out, so tell us the callout when you order and we will make sure the paperwork names it.

Need a BMS 5-133 quote or a Nitto P-55 cross-reference?

Send us your spec callout, the color you need — Class 1 beige or Class 2 black — and the quantity, and we'll confirm the right Polyken 108FR product, stocked widths, lead time and pricing. A Certificate of Conformance is included with every order where available.
