Achieve Unmatched Pressure Protection with the Lee Burst-Sert™ Rupture Disc
When precision matters, trust the Lee Burst-Sert™ Rupture Disc for reliable overpressure protection. Engineered to provide reliable, high pressure relief in a leak-tight, corrosion resistant package, the Burst-Sert™ ensures retention and prevents any bypass leakage without the use of threads or elastomeric seals.

High Pressure Safety Relief Valves
Built to handle severe operating pressures up to 5000 psi, preventing instability and damage. Available in various cracking pressures. The Hi-Q PRV is a line-removable unit designed for high-pressure, high-flow applications. It relieves up to 5400 psid and 19+ GPM, with a side inlet to minimize size and weight.

High Flow Pressure Relief Valves
The Hi-Q PRV is designed for applications that require both a high relief pressure and a high flow rate in a line removable unit (LRU). This valve can relieve pressures up to 5400 psid and flow rates over 19 GPM, and uses a side inlet flow path to minimize the installation boss size and weight.

ZERO LEAK RELIEF VALVES
Instead of relying on a metal-to-metal seal, these valves incorporate an elastomeric or polymeric seal for a zero-leak design, perfect for when eliminating leakage is a critical requirement of hydraulic or pneumatic applications.

NACE Compliant Relief Valves
The 0.281-inch NACE Compliant PRI® valve is built for harsh environments, using corrosion-resistant materials per NACE MR0175/ISO 15156. Available for pressures up to 3000 psi (screened/unscreened) and 5000 psi (screened).

Insert Style Pressure Relief Valves
Lee insert-style pressure relief valves offer secure, threadless installation with integral locking, eliminating leakage. Available in ball and poppet styles, they ensure fast response, stable flow, and high cracking pressures up to 220 bar.

Press-In Style Pressure Relief Valves
Lee press-in-style pressure relief valves feature a barbed design for secure installation in plastic housings, preventing leakage. Available in sizes from 2.5 mm to 8 mm, they ensure low leakage, repeatable cracking, and compatibility with various fluids, including medical-grade applications.
Lee Burst-Sert™ Rupture Disc
DESIGNED FOR DEMANDING APPLICATIONS WHERE PRECISION AND RELIABILITY ARE NON-NEGOTIABLE
The Lee Burst-Sert™ Rupture Disc is a single-use isolation device that provides reliable, high pressure relief in a leak-tight, corrosion resistant package.
The Burst-Sert is designed to seal a passageway or volume until the rated burst pressure is exceeded. At that point, the rupture disc in the plug ruptures, creating a flow passage as large as Ø.25″ (12 Lohms*) to relieve the excess pressure or allow flow to/from the isolated system.
- Burst Pressures from 3000-15,000 psid
- Burst Tolerance +/- 10%
- Operating temperatures up to 450F° (232 C°)
