NBR Nitrile Hammer Union Seal Rings for 1, 2, 3, 4 and 5 Inch Connection Enquiries
Application:
NBR nitrile hammer union seal rings are replacement sealing elements for compatible hose and pipe union connections used in oil-drilling equipment. Specify the nominal connection size, union figure and original seal drawing so that each ring matches its intended groove.
Product Description
A hammer union comprises of a thread end, a nut end and a hammer nut which, when cinched up, compresses a composite seal assembly thereby preventing leakage. The seal assembly comprises a metal insert of a size to pass into the seal groove of conventional hammer unions and a small seal acting between the insert, the thread end and the nut end. The small seal is conveniently an O-ring or a Hammer Union Seal (Lip Seal) and is of a size that is compressed when the seal assembly is inserted into the thread end of the hammer union.
The hammer union is the complete metal connection; the seal ring is its replaceable sealing element. Figure references including 602, 1002, 1502, 2002 and 2202 require their own manufacturer drawing and groove confirmation. Seal rings must not be assumed interchangeable between figures.
Available size : 1", 2", 3", 4" and 5"
Material:
NBR (nitrile/Buna-N) is the material focus of this listing. Specify the exact compound and Shore A hardness for each size. HNBR and FKM are separate elastomer options; PTFE is a separate thermoplastic option and requires its own design review.
Shanghai Qinuo Industry produced a full line of Hammer Union Seals.
For Figure 1502 replacement enquiries, match the seal profile and any brass or stainless steel support ring to the original connection drawing. Working pressure and proof-test requirements belong to the complete union assembly; confirm the manufacturer rating, service conditions and applicable test records. A seal material or nominal size alone does not establish a pressure rating.

NBR Union Seal Size Orders: List Each Connection and Seal Drawing Separately
For a mixed order covering 1, 2, 3, 4 and 5 inch nominal connections, list one line per union figure, size and seal part number. Include inner diameter, outer diameter, section dimensions and quantity. Confirm the drawing for a 5 inch enquiry rather than scaling dimensions from a smaller seal.
Separate plain rubber rings from brass-supported and stainless-supported constructions. Identify the support material and geometry on the drawing. A lip seal, an O-ring and a composite seal assembly are different constructions and must match the original groove.
Provide the oil or drilling-fluid formulation, additives, operating temperature, pressure cycle and storage requirements for NBR compound review. Black color and a hardness range do not establish oil compatibility, sour-service suitability or the final connection rating. Request dimensional and material acceptance criteria with the quotation.
