Hammer Union Seals for Cold Weather Applications
DMR Hammer Union Seals are available in a range of configurations and materials to match the specific performance requirements of your demanding operating environments. For Canadian cold weather applications both our NBR and HNBR elastomers are low temperature rated to -50°C. For applications requiring extrusion resistance our NBR seals are available with a Brass reinforcing rings and both HNBR and Viton Hammer Unions Seals are available with Stainless Steel reinforcing rings. The hammer union seals provide positive sealing with minimum torque. The seal snap-fits into a detent within the hub to prevent its loss. Hammer union seals are available for 1 in. to 4 in. line pipe sizes.

Large HNBR O-Ring Inventory for Oil & Gas Industry
Hydrogenated Acrylonitrile Butadiene (HNBR), also known as Highly Saturated Nitrile (HSN) is superior to NBR in low brittle temperature, heat, oil, oil additive and sour oil resistance, and is far more resistant to sour gasoline and ozone than NBR. HNBR is ideal for industrial products normally made of NBR, and can be used in more severe conditions with much longer service life. To meet the increased demand for HNBR O-Rings in Cold Weather Oil and Gas applications our HNBR o-rings are now rated to -50°C and available in 70, 80 and 90 durometer.

Custom Flange Protection
Used in applications to cover the full face of the flange and to protect the sealing surface. DMR flange protectors are manufactured in a range of materials including: Corrugated plastic, HDPE plastic, MDF or Plywood. Custom profile shapes can be cut to the flange OD for your specific application, while still using the same bolt centre holes as standard flange protectors. We offer a complete range of sizes 1/2" thru 42" and flange protectors can be cut to match any API Specification Pressure Class size from 150 lbs. to 20,000 lbs. Most standard sizes are in inventory.
