Top 8 Sealing Product Recommendations

Based on Guanlu's machine types (BTA, gun drilling, honing, SRB) and the industries they serve (hydraulic cylinders, oilfield, coal mining, molds, automotive, aerospace), these Fluidseal AB product categories deliver the highest relevance and sourcing value.

Metric / Rod Seals
Metric Rod Seals
RA, RC, RX, RZ, SD/N ST/N families
High
Guanlu's BTA and SRB machines produce hydraulic cylinder bores that require high-quality rod seals to prevent fluid leakage along the piston rod. The metric rod seal catalog covers a wide dimensional range with multiple lip profiles suited to the high-pressure, long-stroke cylinders produced on Guanlu equipment.
Hydraulic cylinder rod sealing on cylinders and piston rods manufactured or finished on Guanlu BTA drilling and SRB machines — hydraulic, oilfield, and coal mining industry end-products. Shop →
Metric / Piston Seals
Metric Piston Seals
PB, PB/N, P2B, P5B, P4A, AQ families
High
Piston seals are the primary dynamic sealing element inside hydraulic cylinders — the core product of Guanlu's customer base. The metric piston seal range offers single-acting and double-acting profiles across a broad bore range, directly matching the 20–800 mm cylinder bore diameters produced on Guanlu drilling and honing machines.
Dynamic bore sealing in hydraulic cylinders, servo cylinders, industrial cylinders, and coal mining hydraulic support columns processed on Guanlu machines. Shop →
Metric / Rod Wipers
Metric Rod Wipers
WA, WC, WN, WO, WT, WW families
High
Rod wipers (scrapers) protect cylinder internals from contamination by scraping dirt, chips, and coolant residue off the rod during retraction — critical after the precision bore finishing that Guanlu's SRB and honing machines deliver. The metric wiper catalog lists 15 series covering a wide rod diameter range.
External contamination exclusion on hydraulic cylinder rods in hydraulic, oilfield, and coal mining equipment — extending the service life of cylinders whose bores were processed on Guanlu machines. Shop →
Metric / Guiding Elements
Metric Guiding Elements (Wear Rings / Guide Rings)
GC, GB, GB/N, DU, DZT families
High
Guiding elements (wear rings) absorb lateral forces and prevent metal-to-metal contact inside the precision bores produced on Guanlu machines. The GC series alone lists 1,591 matches, and DU bushings provide self-lubricating guidance — both essential in the long, heavy-duty cylinders made for oilfield and mining customers.
Radial load guidance and bore protection inside hydraulic cylinders, drill collar assemblies, and coal mining supports manufactured using Guanlu drilling and boring equipment. Shop →
Metric / O-Rings
Metric O-Rings
O'ring M (19,953 matches), Quad Rings, Usit Rings, SD/T, SD/U
High
O-rings are the universal static and low-dynamic sealing element used throughout hydraulic valve blocks, cylinder end caps, and fluid ports — all of which are drilled on Guanlu's BTA and gun drilling machines. With nearly 20,000 metric SKUs and specialty variants including Quad Rings and Usit Rings, this is a foundational product category for Guanlu's customers.
Static face sealing and port sealing in hydraulic valve blocks, cylinder end caps, and fluid system connections on components drilled with Guanlu equipment across all served industries. Shop →
Metric / Shaft Seals
Metric Shaft Seals (Rotary Lip Seals)
SC, TC, SA2, SB2, TA2, TB2, VB, VC families
High
Guanlu's machines use high-speed rotating spindles and hydraulic drive shafts that require rotary shaft seals to retain coolant/oil and exclude chips. The metric shaft seal range covers the most common lip seal types (TC, SC) with over 2,200 TC matches and 3,400 SC matches, spanning spindle and gearbox shaft diameters typical in deep hole drilling equipment.
Rotating shaft sealing on machine tool spindles, gearboxes, and hydraulic motor shafts — both within Guanlu's own machinery and in end-products built by Guanlu's customers. Shop →
Metric / Vee Packings
Metric Vee Packings
V1, V3 series
Medium
Vee packing stacks (chevron seals) are used in high-pressure reciprocating applications such as BTA drill head coolant glands and hydraulic cylinder pressure intensifiers. They offer adjustable sealing force and excellent performance under the high-pressure coolant conditions (exceeding 10 MPa) described in Guanlu's medical and precision gun drilling applications.
High-pressure gland sealing on BTA drilling system coolant circuits, pump plungers, and reciprocating hydraulic actuators used in oilfield and mining equipment. Shop →
Hard Parts
Hardened Steel Bushings & Shims
Hardened Steel Bushings (I), Hardened Steel Bushings (M), Hardened Steel Shim, Lock Nuts
Medium
Hardened steel bushings and shims are precision mechanical components used as bearing surfaces, spacers, and locators inside heavy machine tools and hydraulic cylinders alike. Fluidseal AB's Hard Parts category includes inch and metric bushings plus shims and lock nuts — directly complementary to the precision bore work performed on Guanlu BTA, honing, and SRB machines.
Bearing and locating surfaces within hydraulic cylinder assemblies, deep hole drilling machine spindle housings, and tooling support structures produced or serviced by Guanlu customers. Shop →
