How does the Brass End Gland for FR103 & FR104 open the check valve to ensure accurate pressure measurement and switch operation?

The Brass End Gland for FR103 & FR104 opens the check valve by being inserted directly into the interior of the FR end where its precisely machined profile engages the valve mechanism. Once seated, the brass gland pushes the check valve slightly open or holds it in the correct position, creating a clear path for the system pressure to reach the sensing port. This direct mechanical actuation ensures that pressure is transmitted without delay or leakage, allowing accurate pressure measurement and reliable triggering of pressure switches. Made of high‑quality brass, the gland maintains a tight, wear‑resistant fit that preserves consistent operation over time, ensuring repeatable valve opening and dependable switch performance even under demanding conditions.

Can the Brass End Gland for FR103 & FR104 be used with other FR-type ends or only FR103 and FR104?

The Brass End Gland for FR103 & FR104 is specifically designed to fit and operate within FR103 and FR104 type ends. Its dimensions and function—inserted into the interior of the FR end to open the check valve—are tailored to those two end types to ensure proper seating, reliable valve actuation and accurate pressure measurement. While the brass construction and robust design provide durability, compatibility with other FR-type ends is not guaranteed unless those ends share the exact internal geometry and valve arrangement of FR103/FR104. Using it in different FR-type ends risks improper fit, failure to open the check valve, inaccurate readings or damage. For safe, reliable operation, use the Brass End Gland for FR103 & FR104 only with FR103 and FR104 unless the manufacturer confirms compatibility with other specific FR-type ends.
