Elastomer 1502 Union Lip Seal Gasket With Buna W/ Stainless Steel Backing

Figure 1502 Buna Union Lip Seal with Stainless Steel Backing

Specify this Figure 1502 Buna (NBR) lip-seal replacement by nominal connection size and the mating groove drawing. Confirm stainless steel backing dimensions and grade with the seal construction. The backing and figure designation do not independently establish the pressure rating of the complete union.

Other union figures use separately specified groove and seal geometry. Confirm the Figure 1502 lip profile and orientation rather than selecting a ring from the general size list alone.
Provide the exact NBR compound, hardness tolerance, service fluid and operating cycle. FKM and HNBR alternatives need separate qualification. Brass-backed or rubber-only constructions require dimensional review. Sour-gas service requires compound-specific test data; PTFE and PU alternatives need separate grade and fit approval.

Figure 1502 stainless-backed order details:

Seal profile: Supply nominal size, actual ring dimensions and the approved groove drawing revision.
Stainless steel backing: Specify grade, thickness, diameters and installation arrangement against the seal drawing.
Service review: Include fluid additives, temperature and pressure cycles with the complete assembly rating and compound requirements.
Inspection: Check the rubber lip and metal backing for damage and confirm the groove condition before replacement.
Send the Figure 1502 groove and backing drawings to review the Buna replacement configuration.
