Diaphragm Seals - Type 310, All-Welded

Product catalog summary

Overview: The Type 310 "Mini" Diaphragm Seal is a compact, all-welded device designed to protect pressure measurement instruments such as transducers, mini-switches, and small pressure gauges from corrosion, plugging, or freeze-up. It is particularly suitable for space-restricted areas.

Specifications: The seal is rated for a maximum pressure of 2500 psi at 100°F. It features a standard fill/bleed connection and is constructed entirely from metal to prevent leakage of process media.

Materials: The diaphragm and bottom housing are made from 316L Stainless Steel, with options for Hastelloy C and Tantalum for specific applications. The top housing is standard in 316SS.

Connections: The process connection is available in 1/4˝ or 1/2˝ NPT, while the instrument connection is 1/4˝ NPT.

Filling Fluids: The seal can be filled with Glycerin, Silicone, or Halocarbon, depending on the temperature range and application requirements. Glycerin is suitable for direct pressure service from 0 to 400°F, Silicone for direct or flexible line service from -40 to 600°F, and Halocarbon for use with strong oxidizing agents from -70 to 300°F.

Ordering Information: The typical order code is structured as 25-310SSL-02T-CG, indicating the process connection, type number, diaphragm material, bottom housing material, instrument connection, and filling fluid.

Additional Notes: The seal is designed for use with most 3 1/2˝ and smaller size gauges, with a minimum pressure range of 100 psi. For applications requiring ranges below 100 psi, consultation with the factory is recommended.
