Factory Mutual Global Insurance, an international leader in the third-party certification of fire protection products, rigorously tests and evaluates HDPE fire protection products to ensure they meet strict quality standards.

If it has the “FM APPROVED” mark, you know it’ll get the job done right.

We carry these FM Approved pipe products for underground fire protection systems:
• Class 200psi (SDR11)
• Class 250psi (SDR9)
• Class 335psi (SDR7)

Tested to Withstand Intense Pressure
Underground fire protection systems demand pipes that can handle
serious stress. They must withstand high pressure, environmental factors,
and external forces, ensuring reliability and safety in emergency situations.

Factory Mutual won’t give piping products its stamp of approval until they’ve passed strenuous tests that evaluate their strength and integrity.


Gajeske’s FM Approved HDPE pipes undergo a hydrostatic test at four times the pipe's pressure class for five minutes and a stiffness test to ensure they won’t deflect more than 5% when properly buried up to 25 feet deep.


FM certification is your assurance that our products don’t just meet standards — they exceed them. They’re proven to deliver reliable water flow and superior performance under the intense pressure of fire protection systems.
